Description

M31 untracked with DSLR, 250 mm, f6.3, 220 x 2.5 sec @ ISO 6400, darks, flats, bias stacked in Deep Sky Stacker, and a lot of Photoshop time to get the little information out of the huge noise... Image resolution had to be reduced a lot, imaging directly at 50-100 mm might be a lot better.
