The goal for the middle portion of the total eclipse was to capture a wide range of bracketed exposures to pull out the distant corona. This image shows the result of one optional HDR processing technique.
The exposure bracketed images were loaded as Photoshop layers and manually aligned. Next, the opacity of each layer was reduced, allowing the next-lower layer to show through. The lowest included layer's opacity remains at 100%.
This image was modestly cropped from the top right to center the sun, but it shows an expected result from the 840mm focal length. This angle of view fills a substantial portion of the frame with the corona.
Want to contain the corona streamers within the frame? Do not use the brightest exposures in the HDR stack. The center image in the Total Solar Eclipse Phase Progression image illustrates this strategy.
