Description

M101, from my backyard in heavy light pollution. This is old data from last summer that I combined with shots from last night. IIRC last year, this was one of my first try doing 120s shots and I was afraid to burn the galaxy in light pollution, so I spent 2 night on 800ISO instead of 1600ISO... Facepalm... Anyway, over 4 nights, 222x120s, and more experience with photoshop, it looks like a ghost in the sky but that's the best I can do.
