Thanks guys. Yeah, I'll have to have another look at noise and green. I didn't want to make it over processed. Actually I should have posted a scaled down version to AstroBit really - my rig oversamples for seeing etc at best of times, so a cropped in view for a galaxy from the burbs is bound to look noisey. Hadn't planned to let people get that close to the "canvas"
Ah well, you learn something everytime you post.....
EDIT: Hmmm - Actually I've just seen it in the dark and there is a bit too much noise in the there for my liking even in the small jpg.
