Beautifully handled colour saturation and background too.
thanks very much M & T. You are right, the patterns do look like cloud layers - amazing that similar physics seems to apply to both stars and molecules.

thanks Rick - I couldn't find many other images either, not sure why..

thanks very much Marcus. I love it that modern imaging gear can pick up the faint background fuzzies - pity we cannot get more resolution on some of them.

I'm starting to "loathe" my imaging location! I spend 90% of my time trying to restore data from the horrors of LP.... Anyway, your usual great work on a very pretty subject.

Peter
thanks Peter. My site is in the middle of a small country town and I have two streetlights illuminating my obs and sodium site lights at a nearby dolomite crushing plant and grain loading terminal. The sky is not really dark unless the atmosphere is very clear and under the best conditions it can get down to about one mag brighter than full dark (estimated). I don't bother trying to image below ~50 degrees above the horizon, to keep out of the worst LP.
I don't have my imaging computer with me and will post details when I get back to it - from memory, about 70 lum at 5 minutes 1x1 and maybe 2.5 hours each of the colours at 2x2 binning with 180 sec G and R subs and 300 sec B.

I had not observed this galaxy before,your image prompted
me to observe it tonight with my 16" and a 6mm radian.
It has a very bright center which seems off set.
Takes magnification well.
Foreground stars to 13.6 mag seen.
Thanks Ray.
Cheers
thanks for that Ron. I haven't looked through a scope for a while - maybe I should.
