I haven't done color astrophotography work in a few years as I've been hunting asteroids every second I'm out with the scope. I have learned quite a bit about image processing over the last few years and thought it would be fun to do a quick run on M31 (Andromeda Galaxy) under a bright moon to see if I could really bring out some of the dust lanes in the galaxy. After building a monochrome luminance image, I was really happy with it so I took some color data I had shot in 2013 with my DSLR and combined the two to create an LRGB image of the Andromeda core. Pretty happy with how the inner dust lanes popped out. Enjoy!
