Thanks for your comments Steve and John. Using a DSLR there is a fair amount of noise. I was a bit scared to denoise it too much. The top R hand corner could be stacking artifact or residual gradient. There was quite a bit of light gradient. I am on the northside of Brisbane and was photographing to the north away from the city lights but there is a lot of light pollution still. I have noticed it has gotten a lot worse in the 5 years of observing from my backyard. I now probably can't image any closer to the northern horizon than this. I think there is a bit of star glow about the lower R galaxy but I agree there is noise here in my image as well. I orignally processed an image with half as much data. Doubling the amount of data did reduce the noise a surprising amount.
Cheers, Rob.
