...did you process this on a different monitor or lappie perhaps...? There are pretty obvious processing artifacts in a ring all around the galaxy, the main part of the galaxy is really grainy and the background is unnaturally smooth in comparison. Sorry to sound critical but just being honest, I am sure there is a good image in that data and I love this galaxy but ya've kind'a made'a mash of it dude
...sorry. The Ha regions are standing out nicely though
....try again?
