Here is the final result from the Total Lunar Eclipse of May 15-16, 2022. This is a high dynamic range (HDR) image, in that two integrated images were combined to form the final result. The starscape background and the moonglow were captured in a 60 second exposure. Then at mid eclipse, a 1/2 second series of images were shot (10xR, 10xG, 10xB). The resulting stack was combined with the longer exposure to produce this image.
