It seems that, every time there is an astronomical event scheduled, the sky turns cloudy where I am. I'm sure that this is one of Murphy's laws, but ... sometimes everything works out anyway.
This particular lunar eclipse was happening early in the morning and I setup my gear the evening before. After checking the weather report immediately prior to going to bed, I turned off the alarm. The odds of the cloud cover clearing were very low and I decided that a clear mind from a solid night of sleep was the wiser decision.
Fortunately, my Mother-In-Law was wiser than I was (or more excited about the event) and, upon seeing some clearing in the sky, she called me at 4:30 AM. I crawled out of bed, dressed warmly, hauled the ready-to-go gear out to the front yard and found a chair to sit on. I established the focus distance and changed the lens to MF. I then established the exposure needed to keep the moon very slightly darker than blown (mostly avoiding pure white/blinkies on the LCD). The clouds indeed cleared (mostly) by the time of the event and I was able to capture many good shots.
As is generally the case with landscape photography, I had to embrace what the weather provided me and in this case, some remaining clouds moved across the moon at times during the eclipse. The brightness of the moon was much for the clouds to remain visible in the frame most of the time (except when the moon was very obscured), but I wanted to show the clouds in some images with the moon only slightly obscured. Thus, I used an HDR
technique involving two exposures stacked and merged in Photoshop.
The result of this particular image is that the eclipsed portion of the moon is not as dark (due to the presence of the clouds) as those captured without clouds, but the clouds appearing to radiate from the moon yields a different look to this infrequent occurrence.
Obviously, for this lunar eclipse, I opted to fill the frame with just the moon vs. including a landscape in the frame. The 600mm f/4L IS II is a much-appreciated part of my kit, and this was an instance where the 2x extender proved useful.
