Description

Here's attempt 2F of the Andromeda Galaxy (M31). After many many different adjustments and tests, this is the best one so far. Just under 7 hours of total integration time, add another 50% of that for editing and messing around. Ultimately I went back a few steps and removed the stars and really toned them down, adjusted the galaxy separately and then recombined.

I didn't have much exposure time on this one and I had a few previous attempts where I took way too many very short images that took too long to integrate, even on my monster rig.

Perhaps next time I'll go for a lot more integration time, integrate Ha and reduce the core size.
