Thank you, Luke. I didn't like this work, because the colors are very false. I worked with strong light of the Sun. And now, night for me, the colors are very artificial.
This galaxy is very faint. You can see that I used 1 hour and 24 minutes. Subs with 4 minutes and ISO 800.
Perhaps a version mono (BlackWhite) sould be better.
Well, but why not try a reprocessing.
