Needles Eye and Milky Way, Custer State Park, Black Hills, SD Needles Eye and Milky Way, Custer State Park, Black Hills, SD
 

I scheduled three days to photograph Custer State Park in South Dakota. Those three days included two significant travel days and followed a nearly 1-week-long photo trip in Badlands National Park. On that day, the plan was for my daughter and I to scout from Spearfish Canyon down into Custer State Park.

Upon arriving in the park, the highest priority was to scout a milky way photography location in The Needles, featuring incredible rock formations. A Needles Highway closure foiled that plan. An unfortunate person's camper was stuck in the Needles Tunnel, a peril relatively easy to encounter in this extremely narrow tunnel.

After checking in to the hotel mid-afternoon and grabbing a bite to eat, my daughter and I drove the Custer State Park wildlife loop in search of wildlife subjects. That endeavor was mostly unproductive, with only the donkeys cooperating on this evening.

Exhausted from driving all day (and a rough schedule for the prior two weeks), we opted to sleep in the next morning. With the camper now extracted from the tunnel, the original Needles Highway scouting mission was completed late on our only full day in the park. The perfect position was established, and with help from The Photographer's Ephemeris and a compass, it was determined that the milky way would ideally align just before 3:30 AM, just before the sky started brightening in the morning (nautical start).

Hotel checkout was in the morning, and a 7-hour drive to the airport was on the must-do list. Thus, a reasonable amount of sleep was required for a safe drive. However, the National Weather Service forecasted the clouds to (finally) dissipate at approximately 2:30 AM, the already set moon meant that the sky would be dark, and I couldn't pass up this opportunity. So the alarm went off at 2:30 AM. We jumped into warm clothes and drove to the selected site.

While it was the middle of June, the air temperature was low and the sustained wind speed was extremely high. Tucking into the rock spires helped reduce the felt wind, and the high-performing Really Right Stuff TVC-24L Mk2 Tripod and BH-40 Ball Head combination took care of the remaining stabilization requirements. Every frame the Sony Alpha 1 and Sony FE 12-24mm f/2.8 GM Lens captured on this shoot was tack sharp.

Upon establishing the ideal composition, with manual focus on the stars, images were captured in quick succession (as quick as 25-second exposures permit) to ensure the perfect alignment among the needles spire formations, including the Needles Eye, was captured. Also captured was an increasingly bright blue sky, providing a range of options to choose from later. As the new day dawned, the sky continued increasing in brightness, with the foreground brightening as well. Once the milky way had passed through the optimal alignment among the spires, it was time to do some light painting for foreground compositing options.

My light painting flashlight of choice is the Black Diamond Spot 325 Headlamp. This small, lightweight headlight is an excellent all-around choice for outdoor photographers, featuring an extremely bright spot light for navigating in the dark, a red light for preserving night vision, and lower-power floodlight that casts a wide, even light, perfect for many uses, including light painting. The duration of the light panning across the scene was informally measured by counting and adjusted from frame to frame to create varying brightness options.

To gain improved directionality to the light painting, the flashlight was positioned around the far side of the nearby rock spire. The 10-second self-timer provided time to run to this position after the shutter was released.

At 4:00 AM, the milky way was no longer visible. Tired but exhilarated, we packed up and headed back to the hotel for second bedtime.

As so often is the case, the memory of the tiredness, coldness, and effort required for this shot was short-lived, already faded. However, the photos and positive memories will last a lifetime.

Note that a benefit of shooting at this time of the day was that, not surprisingly, we didn't see another car or person during this entire shoot.

From my perspective, the heart of the milky way sets up a superb image. A reflective high mountain lake that nearly meets the sky and the character of spruce tree tops substantially raise the bar.

When the Sony Alpha 1 and FE 35mm F1.4 GM Lens are on the tripod in front of that scene, special results await.

Many focal lengths work well at this location, and the milky way will vertically fill the frame with the entire available range. But, I love how the milky way fills out the frame horizontally at the 35mm full-frame angle of view.

The 35mm magnification is stronger than more commonly used focal lengths, including 14mm, 20mm, and 24mm. Therefore, a slightly shorter shutter speed to avoid star trails is required relative to when the wider angle choices are used, but f/1.4 has you covered.

If you have never photographed the milky way from a dark location with an f/1.4 lens, you don't know what you are missing. I'll warn you — addiction awaits. The FE 35mm GM lens is an outstanding choice.

The Really Right Stuff TVC-24L Mk2 Carbon Fiber Tripod and BH-40 Ball Head never let me down for long exposures.

Images don't always tell the full story. In this case, a persistent wind caused stretched star reflections for most of the several hours I spent at this lake this night. Fortunately, I was blessed with still water for about one or two minutes just as the milky way rotated into the perfect position. With that combination, the rest of the evening's images will likely remain archived.

Alien Throne and Milky Way, Valley of Dreams, New Mexico Alien Throne and Milky Way, Valley of Dreams, New Mexico
 

Photographing Alien Throne in the Valley of Dreams, near Bisti Badlands, De-Na-Zin Wilderness Area and Ah-Shi-Sle-Pah Wilderness Area was on my to-do list, and obviously, I made that trip happen.

You've heard it said that a photo should tell a story. I agree that telling a story is a good aspect of a photo, but storytelling is not always important, and oftentimes, the capture of an image creates a story. This image falls into that latter category.

Some images are complicated to capture, some images are complicated to edit, and some images are both. Again, this one landed solidly in the latter category.

Even beyond any travel required to get to New Mexico, getting to Valley of Dreams requires a long drive (for everyone) that ends on high-clearance two-track "roads" (and a popular mapping app does not currently provide the correct directions). Once driving capabilities are exhausted, the hike to Alien Throne is nearly two miles with, at least for the newcomers, GPS guidance over the trailless desert.

The Valley of Dreams is a dark sky location, optimal for photographing the Milky Way. Add darkness to the hike, and even most Valley of Dreams-experienced hikers need constant GPS navigation assistance as your vehicle becomes a needle in a haystack on the return hike.

Choosing to photograph the Milky Way in April means a middle-of-the-night shooting time (with, likely, no other photographers competing for your location). After photographing a sunrise, napping, scouting, and photographing sunset at Alien Throne, and resting back in the SUV for a couple of hours, we started the second hike to Alien Throne in the darkness at 1:00 AM.

Once in position, establishing the composition was the first goal, and darkness greatly increases this challenge. I brought low-level lighting for this scene, but we opted to go with natural lighting due to the myriad of hard shadows present here.

With the composition established, the Milky Way became the focus. The lens was manually focused on the stars, and the mental note for a quick return to optimal infinity focus was that this setting was immediately after the camera's distance meter changed from a number to the ∞ symbol.

I was uncertain where the Milky Way would be compositionally ideal as it rotated through the image, and there were clouds that could shut down visibility later. Thus, images were continuously captured until the Milky Way was clearly rotated beyond the optimal position.

Next, without moving the camera, the foreground was focused on. The 24mm focal length at f/1.4 does not provide adequate depth of field for this entire scene, making focus bracketing important for that goal.

The ground subjects would not be obscured by clouds, and they were not moving in relation to the camera. Thus, they could be photographed at leisure, and longer exposures created a brighter image without concern for star trails. For this image's foreground, three 30-second images were captured at three focus distances, with the duplicate images enabling some of the noise to be averaged out.

After the blending, the three foreground images were focus-stacked into a single image. Focus stacking is easy in Photoshop (& Lightroom). Open as layers in Photoshop, select all layers, select Edit > Auto-Align Layers [select Auto], choose Edit > Auto-Blend Layers [select Stack Images]. Then, the Milky Way sky image was focus-stacked into the final image.

Further processing primarily consisted of adding contrast, cooling the color tone, and darkening the foreground significantly.

It was after 4:00 AM when we packed up to start the GPS-guided route back to the car, and the sun was up by the time we arrived at the hotel. Hotel breakfast was the end of the story behind this image.

Was the reward worth the effort? Definitely. With photography, it usually is.

Low-Level Lighting Mobius Arch, Milky Way at Alabama Hills, CA Low-Level Lighting Mobius Arch, Milky Way at Alabama Hills, CA
 

Photographing the Milky Way behind Mobius Arch in the Alabama Hills near Lone Pine, CA seemed like a worthy challenge. The arch and other rocks nearby are compositionally complementary to the always awesome Milky Way. Some lighting seemed the optimal method for making the foreground subjects visible in the image, and this time, low-level (low intensity) lighting was the strategy implemented.

Low-level lighting involves setting up continuous lights on the foreground. The requirements for these lights include:

A quality spectrum output is paramount. Just as you care that the entire light spectrum is evenly transmitted through your lens, you care that the full spectrum of light is provided in the first place. Correcting light spectrum issues during post-processing can be a huge, time-consuming challenge, especially if the entire image does not share the same deficiency (such as the sky). Look for lights with a CRI specification of 95 or higher.

While having the entire visible light spectrum equally provided is important, additionally helpful is the ability to continuously adjust the light's color temperature output, enabling emphasis of the foreground feature's color and matching the desired night sky color temperature — try 4000-4500k. Especially important is having warm settings available. Look for lights providing minimally 3200k, and lower is better.

Most night sky photography involving foreground lighting is not done in the back yard. Thus transportation and, often, hiking are involved. Especially when using multiple lights, compactness is a desired trait.

Yes, reducing the size of the light causes the lighting to be harsher, producing a sharper transition into shadows. However, the size of night sky foreground subjects is usually quite large, and the lights are typically placed at a distance from the features, making the size difference between portable lights typically irrelevant.

Compactness means less storage space is required.

Compact lights usually feature light weight, also a feature desired for transport.

Another important low-level lighting feature is continuously adjustable brightness. Light intensity falls off at an inverse-squared (very fast) rate, so the intensity required for one situation can be vastly different from another. For example, the light behind the arch in this image was much closer than the light illuminating the entire scene. Look for a light that provides 1-100% intensity adjustment control in small increments (1% is ideal).

I saved a key requirement for last. Unless lighting distant mountains, the light output needs to be extremely dim.

No manufacturers are saying, "Let's see how dim of a light we can make", and nearly everyone wants their lights to be as bright as possible. Indeed, brighter is better for most photography and videography lighting applications. Ask lighting experts for the dimmest light recommendation, and their eyes glaze over.

However, the night sky is dark, and extremely dim light is required to balance the foreground with the night sky. We are talking about quarter moon phase light levels.

I took three Luxli Viola² 5" On-Camera RGBAW LED Lights for this trip. Aside from meeting the just-shared requirements, the battery is powerful and removable, permitting the lights to be checked on a flight. In addition, a Bluetooth controller app enables the lights to be controlled remotely, an especially helpful option when working in challenging areas in the dark.

While the Viola lights are not the lowest wattage lights, they dim to a much lower intensity than the considerably lower wattage lights I've tried, even at their 1% settings (making me question the accuracy of the 1% setting indication). The Violas use the common NP-F550 Lithium-Ion battery pack. This battery is not tiny relative to the light, but it is long-lasting (especially at 1% lighting levels) and readily available.

On this morning, I carried all of the requisite gear to the location — at 2:30 AM. This time of the day, along with strong wind and low temperature, resulted in complete solitude.

Because of the uneven, rocky scenario behind the arch, the plan was to set up the accent light on Robus Monopod supported by a compact Robus SBM-001 Stabilizing Base. That plan seemed great until I returned to the camera position and heard the distinct sound of a Viola light hitting rock.

Remember that wind factor I mentioned? There was not enough base surface area to prevent the light from blowing over. At that time of the night, it took two such occurrences to prove to me that this light stand was insufficient for the conditions.

A true light stand is a inexpensive, lightweight option for positioning low level lights. After all, holding lights is what they are designed for. However, these need a flat surface (or a weight) to prevent them from tipping over.

Tripods provide significantly more flexibility and stability, and there were two tripods in the MindShift Gear BackLight Elite 45L. Hoped for was that I could shoot with two cameras simultaneously, but the reality was that the Really Right Stuff Ascend-14 Long Travel Carbon Fiber Tripod had to take on the light stand role.

Did I tell you about the wind? While hearing the light hit the rocks twice was painful, hearing the new RRS Ascend-14 go down into the rocks provided that sick feeling you've likely experienced at some point in life. But, unwavering to the challenge (and better educated), I improved the Ascend-14 setup, and there were no more blow-downs.

Noteable is that the Viola light suffered only a scratched plastic housing after falling approximately 4' into the rocks three times.

A second light was positioned on a rock far off to the camera left to provide broad foreground lighting.

The next challenge was getting the lights dim enough for the scene. Even at 1% brightness, the Violas required flagging of much (75%?) of their face. While the flagging requirement left this equipment project incomplete, a high-quality, workable solution was in hand.

I enjoyed photographing the Milky Way until the sky became bright enough to hide the stars.

What is the best neutral density filter for night photography? That is a question you have not likely asked before. However, the 1% light output was too bright, and this project was continued upon my return to the studio. Some of the light had to be blocked.

The Viola lights are not the smallest available models, and if the light requires dimming, why not select a smaller, lighter light to work with? Since I was going to block light, perhaps I could block the extra light coming from more compact LED lights.

The second round of research resulted in a few Simorr Vibe P96L RGB Video LED Lights joining the kit. That the Simorr P96L light specs are solid, and their cost is considerably less than the Violas, are positive aspects.

The Simorr batteries are integrated, meaning the light must be carried onto a plane and that a fresh battery cannot be inserted in the field. However, these lights are so small that they require little space in the first place. The battery drain at 1% is low, and a second light costs only a bit more than a spare NP-F550.

Back to the dimming problem. Neutral density filters are designed to block light, and that is the need being addressed.

You care about the spectrum color neutrality of your lens, and we just discussed the need for your light, but the spectrum color neutrality of your neutral density filter is just as important — and perhaps a bigger challenge to overcome. Color deficiencies can be accounted for during post-processing, but accurately fixing the deficiency requires high-level post-processing skills, along with an image of a standard ColorChecker or similar captured in the same lighting. When the spectrum deficiency is not identical throughout the image (the LED light will not affect the sky color), the color correction skill level requirement increases significantly.

The next phase of this project was to order a Lee Filters Zircon Dark Density 24x24" Gel Filter Sheet. Simply cut the inexpensive gel filter into LED light-sized pieces, and tape them on the lights as needed. Right? That plan seemed ideal until the strong red color cast in the test images immediately disqualified this solution.

Knowing that many threaded neutral density filters have the same problem and that there was a resolution, I gaffer taped a Breakthrough Photography neutral density filter, known to be free of color cast, over the Simorr light. The result was perfect.

While carrying a range of round ND filters in the night photography kit to tape on rectangular LED lights is not optimal, this is the best solution I've found so far. Breakthrough's 100mm square neutral density filters align nicely with the size of the larger Viola lights, but they are an expensive addition to a kit not otherwise using them.

Back to the low-level nightscape lighting strategy. Surely, you have heard of light painting. So here are the low-level lighting advantages over light painting.

What are the Low-Level Lighting Advantages Over Light Painting?

  • Once set up, low-level lights provide shot-to-shot consistency that also facilitates timelapse recording.
  • Less skill is required. Light painting is an art — don't underestimate the skill level required to create even lighting.
  • Many photographers can share a single light setup, regardless of their max available aperture and other camera settings.
  • Low-level lighting preserves night vision.
  • It is easier to light from multiple locations simultaneously without tripping over rocks in the dark to get from one to the other during the exposure time.
  • Low-level lighting does not intrude upon other photographers or those otherwise enjoying the night.
  • Multiple cameras can be operated simultaneously by a single photographer, and long exposures facilitate such.

What are the Light Painting Advantages Over Low-Level Lighting?

  • Provides entertainment and challenge during long exposures.
  • Raises anticipation — brings back the film days excitement of never being certain what the image would look like.
  • Provides a greater variety of lighting in the result set — and a higher failure rate.
  • There is no setup.

Reviewing the Lights:

What are the Low-Level LED Light Requirements?

  • High-quality spectrum output (CRI 95 or higher)
  • Continuously adjustable color temperature output, with 3200k or lower available
  • Continuously adjustable brightness, including extremely dim
  • Compact size, light weight
  • Probably: a method of further dimming the light — flagging or filtering

As shared, the Simorr Vibe P96L RGB Video LED Lights and Luxli Viola² 5" On-Camera RGBAW LED Lights are good options.

Canon EOS R5 Catches Comet NEOWISE Canon EOS R5 Catches Comet NEOWISE
 

The Canon EOS R5 arrived just in time to capture the spectacular night show Comet NEOWISE was providing. Sorry that the noise test results for this camera were delayed by a day, but this was an opportunity I couldn't pass up (at least I waited until after the R5 review was finished to process this image).

The first challenging comet photography decision to make was the desired composition. Including landscape or filling the frame with the comet were the options, and the latter option was chosen. After determining that NEOWISE would nearly fill a 200mm frame, the Canon EF 200mm f/2L IS USM Lens was the chosen lens. The wide f/2 aperture is excellent for use in the dark, and the impressive sharpness of this lens at f/2 means that stars (over 7,000 software-recognized in this frame) remain pin sharp.

The next decision was whether or not to utilize an equatorial tracking mount. A 200mm lens directed at the comet's location in the sky with an ultra-high-resolution imaging sensor behind the lens meant that relatively short images, about 2 seconds, were the limit before star trails became noticeable. On the equatorial mount, 13-second images showed no motion, and this was the option taken. Though the 200 f/2L is rather heavy for the Sky-Watcher Star Adventurer Astro Package, this affordable mount along with the Star Adventurer Mini Latitude (EQ) Base and Counterweight Kit were up to this task. With that much weight riding on it, this mount works best on a solid tripod, and the Robus RC-8860 Vantage Carbon Fiber Tripod was a perfect choice. B&H had just sent me a Robus RTH-1050 Ball Head. It works great, so that option was mounted on the Sky-Watcher.

The R5 was set to manual exposure with 13 seconds, f/2, and ISO 1250 selected. High-speed continuous shooting in 1st curtain shutter mode (this is where I learned that the full electronic shutter does not allow exposures longer than 0.5-seconds). A Canon Timer Remote Controller TC-80N3 was plugged in, and its shutter release was locked on. With the Star-Watcher Star Adventurer polar aligned, the lens framing the comet, including the extensive tail that was not readily seen in the viewfinder, and the camera continuously capturing images, I walked away, watching the comet through binoculars and enjoying a bowl of ice cream.

Despite the night having a clear forecast, clouds showed up in the frame a significant amount of the time prior to the comet setting (while the rest of the sky remained clear). Fortunately, 45 images captured contiguously were able to be made cloud-free with slight cropping. 45 x 13 seconds = 9.75 minutes of exposure, long enough to produce a nearly noise-free image and long enough to capture the color in the ion tail.

While the air traffic is not currently as strong as usual, more satellites than ever are in the sky. Nearly every image had at least one satellite, and some photos had as many as three satellites streaking through. I opted to crop out the clouds before processing the RAW image into 16-bit TIFF files and then removed the streaks using the healing brush tool in Photoshop.

The next task was to stack the images. Stacking comet images is a level of challenge higher than stacking star images due to the comet moving at a slightly different rate than the stars. I know, it is the earth that moves the most, but from an earth-bound perspective, the stars and comet are moving. Stack the comet, and the stars become streaked. Stack the stars, and the comet is stretched. Fortunately, some very smart people created DeepSkyStacker software with an option to align both the comet and the stars.

DeepSkyStacker does a superb job, but you would not know that when looking at the default image created. The low-contrast 32-bit image requires "stretching", contrast significantly increased with colors pulled out. The only adjustments made to this image were contrast (levels and curves to stretch the low contrast 32-bit stacked image), saturation (+10 and -60 in PS), and a white balance adjustment (cooled the image slightly).

I love NEOWISE's colored ion tail, pushed away from the sun by solar winds and separated from the dust tail. BTW, the name NEOWISE uses all capital letters because it is an acronym, named after the device that discovered it.

Now, NEOSWISE is gone, effectively, forever. Comet NEOWISE was awesome but will not be seen again for another 6,800 years. Hopefully, another comet will entertain us in the night sky long before that.

4 Minutes of a Lightning-Spewing Thunderstorm, Badlands National Park 4 Minutes of a Lightning-Spewing Thunderstorm, Badlands National Park
 

With air-to-ground lightning strikes averaging under 10-seconds apart, this thunderstorm was awesome.

After dark, lightning becomes easy to photograph. Mount the camera to a tripod, frame a composition that includes the location with the most frequent lightning, focus to a long distance, set the aperture and ISO to control the lightning and overall image brightness, and then open the shutter long enough to catch at least one strike. Easy is to use 30-second exposures controlled by the camera (the strategy implemented for this example), but the Bulb setting controlled with a remote release enables the exposure timing to be adjusted as desired. For example, lock the remote release button down until there is a strike or the time duration exceeds the tolerance for long exposure noise.

Make safety a priority. Photographing lightning from a safe distance (far away) is advised. Locations with long distance visibility are advantaged in this regard, and the flat midwest prairie gets impressive thunderstorms.

Along with this storm came wind, wind strong enough create significant camera vibrations with even a sturdy tripod and strong enough to put a significant amount of dirt in the air. The solution to this issue was to drop down into the canyon a bit. The difference in wind speed 25 yards (25 m) down from rim was substantial and a solution to the problem.

Right, the title says four minutes, but a 30-second shutter speed was in use. This image is a four-minute exposure created by blending eight 30 second exposures using the "Lighten" layer blending option in Photoshop. This blending option is simple to use, allowing the lightning strikes from the layers below to show through.

As usual, the Canon EOS R5 and RF 24-70mm F2.8 L IS Lens performed impressively on this shoot.

Milky Way, Acadia National Park Milky Way, Acadia National Park
 

One of my favorite subjects to photograph is the Milky Way. The required long exposures provide plenty of time to simply watch the spectacular sky show (unless I'm running two cameras), taking in the awesomeness, and the pictures captured are usually among my favorites. I was blessed with the opportunity to photograph the Milky Way from several top-notch locations this year, including during the Rocky Mountain National Park and Acadia National Park workshops. The image shared here was captured from the coast of Acadia NP.

Seldom can the reflection of the Milky Way be seen in an ocean as the water movement completely blurs everything during the required long exposure. However, tidal pools are often still and can make great reflectors (though not at high tide) for a variety of coastal photography needs including reflecting the night sky. Adding value to this particular tidal pool was the low surrounding rock with good character, adding jaggedness to the rock line and its reflection.

To photograph the night sky, I usually want a wide-angle lens with an f/2.8 or wider aperture available with sharp wide-open image quality. The Canon RF 24-70mm F2.8 L IS USM Lens, with an EOS R behind it and a Really Right Stuff TVC-24L Mk2 Carbon Fiber Tripod and BH-40 Ball Head under it, met those needs superbly.

Photographing the Milky Way is easy and very addicting. This image was captured using the 2-second self-timer feature with settings of f/2.8, 15 seconds (longer exposures increase star trail length), and ISO 6400 (with a low amount of noise reduction applied). I opted to brighten the result a bit in post and brightened the foreground by an additional stop for a single-image HDR. Just after sunset, the sky still had some color in it and a slight saturation increase (+1 in DPP and +7 in PS) made those colors pop. Auto white balance was used. Increasing contrast via an S-curve adjustment always makes the Milky Way stand out.

As I was searching through the over-a-thousand images captured with the RF 24-70, selecting a few to share in the review, this one stood out as my favorite and thus I'm sharing it with you here. Add the RF 24-70mm lens to the list of good night sky lenses.

After Dark at Rock Cut, Rocky Mountain National Park After Dark at Rock Cut, Rocky Mountain National Park
 

I recently shared Rock Cut in the last light. I didn't go home after the sun set, and instead tolerated high winds and very cold temperatures for a couple more hours. It seemed that the rock formations here would make a good foreground for a Milky Way photo.

Getting the rock formations to rise above the other landscape meant climbing down to the edge of the cliff, and low-level lighting was used to bring out the rock color. The foreground lighting in this Rocky Mountain National Park Milky Way image is from a pair of Simorr Vibe P96L RGB Video LED Lights on Manfrotto Befree Advanced Travel Tripods.

Once the lights and camera were set up, waiting (did I mention that it was really cold?) for the Milky Way to rotate into the desired position was the remaining task.

The Sigma 20mm F1.4 DG DN Art Lens is an outstanding Milky Way lens. The difference that f/1.4 makes in Milky Way image quality over an f/2.8 lens is dramatic.

Join me in RMNP this September. I have an opening or two for the Elk Rut in Rocky Mountain National Park Instructional Photo Tour.

My Favorite Milky Way Lens, A Meteorite and Hallett Peak, Rocky Mountain NP My Favorite Milky Way Lens, A Meteorite and Hallett Peak, Rocky Mountain NP
 

As long as the correct exposure and basic compositional skills are applied, it is hard to take a bad picture of the milky way.

Here is a list of steps for photographing the milky way.

  1. You need to be able to see the milky way, and it is not always visible. Find that schedule. The Photographer's Ephemeris and similar apps are useful for this. Mid-late summer is ideal.
  2. You need a dark sky. Dark as in no city lights, even in the distance, is most important, and no moon or a small moon is also helpful. Plan for the dark sky location and moon schedule.
  3. You need a clear sky. Heavy cloud cover is a milky way photography show-stopper.
  4. A camera is required. Most modern interchangeable lens cameras will work fine, but with equivalent lenses, the full-frame models have an advantage.
  5. The camera requires a lens, and lens selection is critical. The lens needs a wide aperture to create a bright enough image in an exposure short enough that star trails do not appear within the acceptable ISO range of the camera. Think f/2.8 as a minimum, and f/1.4 is awesome. A wide-angle focal length is needed to get enough of the milky way in the frame. While 35mm can work, go with 28mm and wider (full-frame equivalent). Stars are pin-sharp and you want a lens that renders them pin-sharp fully into the corners at the wide-open aperture. That lens does not exist, but some lenses are considerably better than others for this purpose.
  6. Mount the camera and lens on a solid tripod and head.
  7. While the milky way looks great without any other supporting environment, an attractive foreground can make such an image stand out, as illustrated in this image.
  8. Focus the camera. If the moon or another very distant light is visible, autofocus on it, and then switch to MF. Otherwise, or alternatively, use manual focus (pick a bright star and fully zoom in to focus manually).
  9. Set the camera to manual exposure, and remember that your LCD is going to appear very bright in the dark.
  10. Use a wide-open aperture.
  11. Set the shutter speed. Basically, use the longest possible shutter speed that does not create offensive star trails. Consider starting at 20 seconds for a 24mm lens on a medium resolution imaging sensor. Higher resolution imaging sensors more readily show star trails and require shorter exposures for equivalent pixel-level results. Review the shot until the ideal duration is established.
  12. Set the ISO. Too high is the setting most often needed. At f/2.8, ISO 12800 is probably needed. At f/1.4, try ISO 3200 or 6400.
  13. Set the drive mode to 2-second self-timer.
  14. Frame the scene as well as possible (it will be very dark), capture an image, adjust the camera, and repeat that process until perfection is achieved.
  15. When the composition is just right, cue the meteorite to streak through an ideal area of the composition. Want a meteorite in the frame? The odds for any given frame to have a meteorite in it is low, but selecting a date within a known annual meteor shower, such as the Leonids, greatly increases the odds. After establishing the perfect shot, set the camera's drive mode to high speed, plug in a remote release with a locking button, lock the remote's shutter release down, and walk away. Tending a second camera setup is a good use of this time. If available, a bowl of ice cream is also entertaining. Come back to adjust the composition for the milky way's movement across the sky (I know, the earth is what moves).

Amazingly, and out of the norm for me, was seeing a meteorite streak by while the shutter was OPEN, without using the continuous drive mode technique. While I welcome meteorites, I do not fancy satellites. They get removed (this is easy with Photoshop's healing brush and clone tools).

As mentioned, the earth rotates, causing the milky way to move across the sky like everything else up there. On this evening, I followed the heart of the milky way around Bear Lake in Rocky Mountain National Park until Hallett Peak was a foundational element in the composition. Despite the 4:30 AM alarm, it was well after midnight before exhaustion overcame excitement.

What is my favorite milky way lens? Currently, the Sony FE 24mm f/1.4 GM Lens holds that title for me. The 24mm focal length fills a significant portion of the frame with the heart of the milky way. The f/1.4 aperture is extremely wide, permitting lower ISO settings for less noise. This lens's image quality at f/1.4 is excellent. The size is compact enough that I can take it along as a lens dedicated to this purpose.

Starry Night at Bald Peak, Acadia National Park Starry Night at Bald Peak, Acadia National Park
 

The top of a mountain in Acadia National Park is a great location to take in a sunset. Better still is to extend that sunset photography opportunity into night sky photography.

It is hard to make a bad composition of the milky way, but adding an interesting foreground usually improves nightscapes. My eye is naturally drawn to mountain peak markers, and the Bald Peak marker was available.

The next step in composing this image was determining the ideal balance of the marker with the milky way, and the camera position illustrated here seemed optimal of the accessible shot locations.

The Sony FE 24mm f/1.4 GM Lens is one of the best nightscape lenses ever made. While the ultra-wide f/1.4 aperture is one of this lens's key nightscape advantages, the 24mm f/1.4 depth of field is shallow, too shallow to keep this sign and milky way sharp. Thus, this capture required an image focused on the peak marker and another focused on the stars.

Post-processing the two image stack was simple. The images were layered into a Photoshop file, and a layer mask was added to the top layer. Painting the mask black reveals that portion of the layer below, the peak marker and rocks in this case.

Back Against the Rocks, Blue Hour Milky Way, Monument Cove, Acadia National Park Back Against the Rocks, Blue Hour Milky Way, Monument Cove, Acadia National Park
 

Sometimes, an ultra-wide-angle lens becomes a requirement to get the shot. Sometimes, a wide aperture is also required. Both were requirements down in Monument Cove, Acadia National Park, on this night. The Sony FE 12-24mm f/2.8 GM Lens had the credentials to get the job done.

As I climbed down into the cove, the plan was to capture the monolith in front of the milky way. Upon arrival, I decided that the rock on the other side of the frame also had great character and wanted it included in the image. Even at the extreme 12mm full-frame angle of view, keeping everything seen here in the frame meant my back was against the rock wall.

The milky way is typically photographed against a black sky. However, if the sky is dark and the milky way is in view, it can be photographed at the end of the blue hour. This image was captured about 7 minutes after "nautical end." Despite a bit of light showing in the sky, it was very dark in the cove, and the f/2.8 aperture proved very helpful, keeping the ISO setting down to a still-high 8000.

My apologies if I missed an important keyword in that title.

Regardless of what the event was named, the show was spectacular. I hope that you were able to take it in and, even better yet, photograph it.

The sky visibility forecast for everywhere within a long drive provided little hope of this eclipse being viewable. Unexpectantly, the problem, remnants of a significant winter storm, began to move out just in time and the sky started to clear about an hour before the eclipse began. With the full moon peeking out of breaks in the clouds, the hope became strong enough to warrant the effort to photograph the event and I scrambled to put a plan into place.

Also seeming to meet the definition of spectacular were the near-zero-degree (-18° C) temperatures accompanied by very strong winds those of us in much of the east/northeast US were required to endure for 5 hours (some short indoor warm-up breaks were taken). Admittedly, the temperature made shooting through skylights from inside the house a very attractive option, but donning many layers and going outdoors became the plan. While the skies cleared beautifully for the full eclipse, the wind remained an issue and wind is an especially big stability problem when photographing with a large, long focal length lens. Setting up next to a solid fence significantly aided with this issue and also took some of the bite out of the wind chill.

The composition plan was easy. The moon was going to be high overhead and that meant incorporating foreground elements in the frame was going to be very challenging, so making the moon as large in the frame as possible was the choice. That meant 1200mm, a combination of a 600mm f/4 lens and a 2x teleconverter.

For a solid base, the UniqBall IQuick3Pod 40.4 Carbon Fiber Tripod with spiked feet installed (for use in snow) was perfect. Simply stick the spikes into the ground and use the IQuick3Pod's leveling base feature to quickly level the tripod head platform. A gimbal head makes using big, long lenses easy and the Really Right Stuff FG-02 Fluid-Gimbal Head is awesome (the RRS PG-02 is also excellent). With a level base, the gimbal-mounted lens will always be level with only tilt and pan adjustments, both very simple to make, requiring attention while tracking the moon. It is much easier to keep a tightly-framed moon centered in the frame with a gimbal head than with a ball head. Shooting at a strong upward angle can be a challenge with a gimbal mount as the camera body can impact the tripod before a high-enough angle is reached. I'll talk more about that issue soon.

Looking through a viewfinder with the camera directed at such a hard-upward angle is tough, but the D850's tilt LCD made subject framing easy in this situation. An angle finder is another great option for shooting upward.

What is the best exposure for photographing a lunar eclipse? That depends mostly on the varying brightness of the moon and that changes by season and it also changes during the eclipse. When the moon had direct sunlight reaching it, f/8 (my max aperture with this setup), 1/200 and ISO 200 with a -1 EV adjustment in post worked well. During this time, I opted to capture brackets of up to 9-stops to use for adding as much detail as desired to the dark portion of the moon during post processing. A Vello ShutterBoss II Timer Remote Switch made vibration-free capture easy.

Once the moon was completely in the earth's shadow, it became very dark and 1200mm exposures became very challenging. The blood moon image in the center of this frame was captured at f/8, .6 seconds and ISO 6400. Getting tack sharp details from a subject that is over 221,000 mi (356,000 km) away does not happen and these settings do not help.

Photographing the lunar eclipse brought back great memories of the 2017 solar eclipse (a bit ironic is that event occurred in extreme heat for many of us). A similar post-eclipse scenario now faces those of us who photographed it. We have a large number of images capturing the entire eclipse progression and want do something with them. While each individual eclipse image may be great, likely none of your friends want to see all 300 (OK, 800) of them. The friends will be interested in a partial eclipse image or two and perhaps one from totality, but then eyes glaze over and they start checking their Instagram account. Creating a lunar eclipse progression composite is a very logical way to tell the full eclipse story in a single, interesting image.

The method for creating the lunar eclipse progression composite is the same as that shared in the How to Create a Solar Eclipse Phase Composite Image article (skip the HDR part). The arrangement options for such a composite vary greatly. The left-to-right option shared here works well, but this unique ultra-wide aspect ratio is a bit awkward to share online and will not typically be as easily viewable/displayable as closer-to-square arrangements.

Also ultra is the resolution able to be created from such a composite. This one measures 52000 x 5500 pixels for a 286 MP (over SmugMug's max file dimensions limit I learned) final image (the .PSD weighs in at 3.19 GB) looking for a long hallway wall to be displayed on. Those not able to frame the moon tightly in-camera can crop heavily and still have a high resolution result from the composite technique.

Sure, getting images requires some effort. Getting to bed well after 2:00 AM means being tired the next day and it took about an hour under the covers to get my core temperature back up. But, at least a day or two later, only the rewards remain. The memories of this lunar eclipse, with the images to buoy them, will remain a lifetime.

What is the subject calling you right now? Get motivated and go for it!

Sony FE 24mm f/1.4 GM Lens, The Ultimate Northern Lights Lens Sony FE 24mm f/1.4 GM Lens, The Ultimate Northern Lights Lens
 

When cost, time, and effort are invested into a photography trip, generally only the best-available gear (or something new being reviewed) makes the pack. Milky way and aurora nightscape photography opportunities were on the potential list for a recent trip, and my three favorite night sky lenses were packed specifically for these subjects.

When the milky way is visible, the scene is extremely dark. While the milky way exposures are long, the earth is rotating, creating a form of action photography.

The aurora has varying intensities and can be pulsing and dancing around the frame. If the exposure is too long, the dancing and pulsing aurora turns into a big smear of color. Thus, aurora photography also involves action, an action that is often moving considerably faster than the earth's rotation.

Wide apertures are a big advantage for stopping action, and each of the lenses included in the above list is the widest available at its respective focal length. Just because a lens has a wide aperture does not mean that you want to use that aperture, as many wide aperture lenses are not sharp wide open, becoming considerably sharper as they are stopped down. However, those in the above list are outstanding performers wide open.

While the f/1.4 aperture is a clear advantage held by the FE 24 over the other two lenses, f/1.8 is still very wide. Motion blur is caused when subject details cross over pixel wells on the imaging sensor. Because the 24mm focal length magnifies subject details more than the 14mm and 20mm options, a slightly faster shutter speed is required to photograph the same subject at the same distance with an equivalent amount of motion blur. This shutter speed difference offsets some of the aperture difference.

Mostly, I selected between these three prime lenses based on the angle of view they provide.

The day started with a 5:30 AM alarm and a long search for moose. Upon returning late morning, we learned that the northern lights forecast was favorable. However, the weather did not appear to be favorable, with heavy cloud cover promising to block all higher altitude subjects. Still, the National Weather Service hourly forecast showed the skies expected to clear at 2:00 AM at our desired viewing location. That time coincided with the moon setting, yielding darker skies.

After a short nap, a 2-hour drive ensued, heading north for darker skies and a favorable viewing location. Intermittently checking the skies, the clearing began right on schedule. Unfortunately, the aurora was not yet apparent to the eye. Dim northern lights are considerably easier to see in a long exposure image, so cameras were mounted to tripods and put into action. Test images showed a small vertical column forming over Denali, the mountain in the bottom of this image.

Initially, the northern lights were small, muted, and stationary. The 24mm lens made the little show larger in the frame than the other two lens options, and also accentuated Denali in the foreground.

The show progressed, significantly increasing in intensity and motion, with this image requiring only a 4-second exposure at f/1.4 and ISO 2500. Eventually, the 20mm angle of view (sample here) was needed to take it all in, and the 14mm angle of view (sample here) became optimal not long afterward.

We pulled into the driveway at 6:30 AM. Aside from a short nap and a few eyes-closed rests, it was a 25-hour day. As is usually the case, I struggle to remember the details of the exhaustion, but the memory of the dancing northern lights is still clear, and the images will last a lifetime, keeping the memory alive.

How to Process Solar Eclipse Exposure Bracketed Images – A Simple HDR Technique How to Process Solar Eclipse Exposure Bracketed Images – A Simple HDR Technique
 

Like scores of others, you (probably) and I photographed the solar eclipse this year. While partial solar eclipse images are easy to process (simply make them bright without blowing the red channel), the total eclipse images when bracketed, are in a different league in terms of complexity. So, like me, you are probably now asking, "How do I process the exposure-bracketed total eclipse pictures?" While there were many articles teaching us how to photograph the eclipse, those telling us how to process the images we captured during totality are scarce.
 
A great solar eclipse photography strategy is to extensively bracket exposures during totality, when the corona becomes visible. While the corona is relatively bright just outside the edges of the moon, it becomes very dim far away from the sun. Of course, with the sun being 93 million miles away, the word "far" takes on a significant meaning.
 
While I hoped I could simply load a set of bracketed-exposure images into my favorite HDR software (Photomatix or Photoshop) and be finished, the results returned were not acceptable to me for a couple of reasons. The primary problem was that the software did not properly align the moon (it moves across the frame in subsequent images), creating ghosting and still did so even if I pre-aligned the moon in each image. I could have overlaid the moon from a single frame, but ... I still wasn't satisfied with the overall look of the results.
 
In the end, after numerous trial and error attempts, I settled on an easy, relatively fast way to merge the results in Photoshop as my solution. Note that there are many techniques that can be used to process a stack of bracketed total solar eclipse images, so don't think this is the only option. But, this technique is easy and it produces a nice result.
 
Hopefully you captured your images in RAW format for the highest quality and in that case, processing those RAW files into 16-bit TIFF format is the first step needed.
 
Next, the images need to be loaded into layers in Photoshop. I use Adobe Bridge for this task, browsing to the folder the files are located in, clicking on the first of the series and shift-clicking on the last to select them all. Then select the "Tools" menu, "Photoshop", "Load files into Photoshop Layers ..." and a new Photoshop document will open with all of the images stacked in layers.
 
Unless you were using a tracking mount, the moon disk will need to be aligned in the layers. I simply moved each layer into identical position. Click on the layer and move it using the move tool. Toggle layer visibility of the image containing the targeted moon position for use as a guide and use the arrow keys to slide the layer being adjusted into position.
 
Once the images are properly aligned, crop the image as desired. Trimming away the missing edges and centering the sun was my decision.
 
Next, Order the layers from top down in darkest to brightest sequence. Because I set up the camera to shoot brackets from darkest to brightest (using three custom modes), this sequencing happened automatically for me.
 
Select the first/top layer and shift-click on the second-to-last layer. With all except one layer selected, reduce the layer opacity using the "Opacity" box at the top of the layers palette. Try starting at 20% and adjust to taste from there. I suggest keeping the image on the bright side at this point.
 
Making the opacity adjustment (likely) immediately produced an image that looks decent, but one ready for some contrast adjustment. Click on the top layer and create a new adjustment layer. The adjustment layer type you should select depends on your Photoshop skill level, but it needs to be a contrast-adjusting layer type that you are comfortable with, curves being the most powerful and levels being very easy. Use the adjustments the selected tool offers to bring life into the image. If using curves, try selecting two points to create an S-curve that darkens the darks colors and brightens the light (though likely only slight brightening is needed if the layer opacities were set low enough). If using levels, try reducing the mid adjustment slider. You may find that adding multiple adjustment layers is helpful. The beauty of adjustment layers is that they are non-destructive and can be created or deleted at any time.
 
Because the edges of the moon become brighter as the exposure becomes increases, the edges of my moon were not as crisp as I liked. Also, Baily's Beads were one of my favorite aspects for the solar eclipse and they were only found in the images captured just before C2 and just before C3. So, I incorporated an additional layer into the top of my layer stack and used a layer mask to make only the lunar disk and Baily's Beads visible. This means a black mask (use CTRL-I with a newly-created mask selected), with the desired visible attributes painted white (I used the paint brush). Another option for sharpening the moon is to duplicate one of the existing layers (CTRL-J), likely a darker one, giving it a 100% opacity and a layer mask with only the lunar disk made visible.
 
A technique that can be used to bring out some contrast in the corona is via Photoshop's High Pass filter. There are a number of ways to do this, but here is one of them:
 
Select and combine all layers by clicking on the topmost layer, shift-clicking on the last and pressing CTRL-E. Then copy the combined layers to the clipboard by press CTRL-A to select the entire image and then pressing CTRL-C to copy it. Next, undo changes until one step back past the layer-combining step. Select the top layer and press CTRL-V to paste in the copied combined layer.
 
With the new layer selected, desaturate it by pressing CTRL-SHFT-U. Implement the High Pass filter selecting from the menu: "Filter" > "Other" > "High Pass...". From the High Pass filter dialog, adjust the radius until it seems like the results will work well, with a low value being good for sharpening hard edges such as the border of the moon and a high value being good for adjusting overall image contrast, such as the corona.
 
The next step is to change the blending mode of the High Pass layer to "Overlay" by using the blending mode drop-down list founds at the top of the layer palette. The opacity of the High Pass layer can be adjusted to reduce the amount of effect and a mask can be used to hide undesirable portions of that layer. You can create a second or even third High Pass layer if you think it will help.
 
Adjust individual or smaller groups of layer opacities is another step that can be taken to optimize the final appearance.
 
For the total solar eclipse HDR image shown here, I combined eight 1-stop-bracketed exposures (out of 14 captured) using opacity values of 100% on the bottom (the brightest frame), 25% for the next three up, 20% for the next three up and 30% for the darkest layer on top. The top layer has a layer mask that allows only the center of this frame to show with a strongly-feathered border creating a natural transition to the layer below (one click in the center with a very large, totally-soft paint brush tool selected).
 
With so many options available, you may decide it worthwhile to create multiple versions of your HDR image and that is a great idea. You worked hard to prepare for and capture the solar eclipse, so having multiple images processed differently simply increases the reward.

Epic Rocky Mountain National Park Milky Way Epic Rocky Mountain National Park Milky Way
 

Sony a7R IV and Epic Rocky Mountain National Park Milky Way The Sony a7R IV and Sony FE 24mm f/1.4 GM Lens teamed for an epic Rocky Mountain National Park Milky Way on this September evening. While chasing elk in rut was our top priority during the RMNP workshops, photographing the night sky was also on the to-do list and a clear RMNP night sky never fails to wow us.

For the Milky Way to reach down close to its reflection requires the reflecting surface to have little obstruction above it. Large bodies of water have distant shores and that distant perspective usually results in lower shoreline sky obstructions. Small bodies of water are more likely to have a calm surface than large bodies but trees and mountains typically get in the way of the little-obstruction requirement. Mountains often bring elevation gain that tends to bring reflection-erasing wind.

This particular small mountain lake is set high enough for the southern view to open up to the sky while being protected from the wind for the perfect combination. I love pointed spruce treetops and always welcome their great character on the horizon. Reflections can be counted on to double the value.

When two wide-angle f/1.4 lenses promoted as ideal for photographing the milky way (an addicting pursuit) show up in the same box with a dark, cloudless sky predicted for the next evening, you drop everything and drive hours to the darkest sky location in the region. In this case, that location was Cherry Springs State Park, an International Dark Sky Park, near Coudersport, PA. After a few hours of sleep and especially after loading the photos from the memory cards, you forget about arriving home at 2:30 AM.

This image was captured with the Sigma 24mm F1.4 DG DN Art Lens, and the Sigma 20mm F1.4 DG DN Art Lens opened up the angle of view slightly. The 20 and 24mm ultra-wide-angle focal lengths are ideal for framing the heart of the milky way, and the ultra-wide f/1.4 aperture allows sufficient light to reach the imaging sensor in the exposure time necessary to prevent star trails.

Here is the Cherry Springs State Park Milky Way at 20mm.

Regulus, Diamond Ring and Total Solar Eclipse 2017 Regulus, Diamond Ring and Total Solar Eclipse 2017
 

One of my goals for the 2017 Total Solar Eclipse was to bracket exposures ranging from no-blown-color-channels to as bright as I could create. Using three custom modes set for AEB (Auto Exposure Bracketing), I was able to capture 21 images with exposures ranging from 1/8000, f/8 ISO 100 to 1 sec, f/4 ISO 800, covering over 18 stops of exposure difference.
 
You may have noted that I was using an f/2.8 lens and could have opened up one stop wider. I decided that vignetting at f/2.8 took away most of the wider aperture advantage in the periphery and, with the sun creating the most light in the center of the frame, the periphery brightness was what I needed most from this frame. So, I opted to stay with f/4.
 
A number of the darkest images in the set proved too dark to be useful. In the brightest image, all three channels were blown in nearly half of the image. Thus, I felt successful in meeting that goal.
 
There was of course a purpose to that goal and that purpose was to create an HDR image that made as much of corona visible as possible. While I also had a 200mm lens deployed with the same purpose, the 400mm angle of view fully contained the maximum corona able to be captured under the slightly hazy Tennessee skies.
 
To create this image, I stacked 14 exposures using (essentially) the solar eclipse bracketing procedure I recently shared. I think that I could continue tweaking this result indefinitely, but ... it is time to label it "finished" and move on to all of the others.
 
In this case, you could say that I got a "star" for effort.

Milky Way and Perseid Meteor, Island Pond, T15-R9, Maine Milky Way and Perseid Meteor, Island Pond, T15-R9, Maine
 

Welcome to Island Pond, located by Red River Camps in Deboullie Public Reserved Land of T15-R9 in the North Maine Woods. That this location is a nearly 1-hour drive from the grid and paved roads should help set the scene. Along with natural beauty, what you get here is a dark sky and at this time in August, a beautiful view of the Milky Way and the annual Perseid Meteor Shower.

Aside from the effort required to get to this location, this was a very easy image to create.
 

  • Mount the camera and lens on a solid tripod
  • Manually focus the lens on a bright star using fully-magnified live view
  • Adjust the composition as desired with the camera leveled for roll
  • Dial in a manual exposure of f/1.8 (use your widest available), ISO 6400 and 30 seconds (a stretch)
  • Set the camera to its high-speed frame rate
  • Plug in a remote release
  • Capture a test image and verify that it looks good
  • Lock the release button down (press down and slide forward)
  • Return later
The camera continuously captures images, hopefully with perfectly-positioned meteors in them. These frames can also be made into a time-lapse.

After setting up the first camera, you have plenty of time, so set up a second camera the same as the first, capturing a different composition.

On this night I had three camera setups with four of what I consider the best night sky lenses available. One of the cameras was a Nikon model and the only Nikon-mount star-capable lens I had along (not a Nikon model) showed a serious image quality problem, leaving two cameras in operation.

I mentioned that the 30-second exposure was a stretch and that is what happens to the stars at this focal length, exposure duration, and imaging sensor pixel density combination. They get stretched.

A blur is created when details in an image move across pixels on the imaging sensor, regardless of the reason why that happens. As we all know, due to the earth's rotation, stars are moving across the frame when the camera is in a fixed position. The longer the exposure, the more they are magnified (longer focal length lens) and the higher pixel density the imaging sensor has, the more that star blur will be visible at the pixel level.

Note that when final images are viewed and compared, the imaging sensor's pixel density-caused blur becomes equalized. For example, if you are printing at 8" x 12", the pixel density factor no longer matters in regards to the star trail blur created by two different resolution, equal-sensor-sized cameras.

Also, note that not all stars move at the same rate relative to the camera position. For example, the North Star (Polaris) does not move at all. If you are primarily including the northern sky in the frame, you might be able to use longer exposures than if your camera was directed west, east or up. There are star blur rules that can be helpful, but photography skills rule. Analyze your results as soon as they are captured and make adjustments as needed.

I mentioned having 4 of my favorite star lenses along with me. They are my favorites, but the perfect star lens, at least from a lens in the realm of affordability for most individuals, does not exist. All lenses have at least some issue keeping them from reaching perfection and corner performance is typically their biggest limiting factor.

This image was captured with the Sigma 14mm f/1.8 DG HSM Art Lens. It is a great choice for this purpose.

For star photography, ultra-wide angles are helpful for taking in a greater area of the sky and allowing longer exposures before star trails become visible, though ultra-wide angles produce rather small stars. Ultra-wide apertures (that produce sharp enough image quality to be used) create a brighter image in less time or at a lower ISO setting. The Sigma 14mm Art lens has those two features.

The worst case: even if the entire night's shoot was a failure, just hanging out under a starry sky would be totally worth the time and effort.
