Description

From the Great American Eclipse of 2017. Taken in Sweetwater, Tennessee with a Nikon D5100 and 200mm telephoto lens at f/2.8, ISO 100. Exposures were between 1/500s and 1/4s. For processing I initially used Russell Brown's tutorial for stacking in Photoshop and sharpening with the radial blur filter method. I did further sharpening with high pass filters. I then opened the image in Pixinsight and followed David Ault's tutorial for creating a synthetic flat. This sufficiently removed the "halo" effect in the center of the image, which was the biggest challenge for me. I then brought the image back into Photoshop and adjusted the levels and used masks to bring color back to the corona. Although I did capture Earthshine, I decided to leave it out for this image. An astrometry.net platesolve revealed 21 stars, 18 of which are actually visible.
