Seeing this is all the rage at present, decided to have a go at it.
This is 5x12mins at 800 iso. A bit of photoshop and cropped. Maybe overdone the processing a bit.
Overall a very good Cent A. A bit magenta biased and you've used unsharp mask a bit hard. Sharpening is best done masked so the stars don't aren't affected only the galaxy. Or do a selection of the galaxy with lasso and feather it then apply unsharp mask.
Good to see an APO Cent A. APO images are always that bit more pleasing.

Greg, you are spot on, I am not real smart with using masking, and I really do need to come to terms with it. Thanks for the tips, all much appreciated.
Tks guys. I find it hard to get color in stars with a DSLR, others manage to, but it seems to evade me. If the stars are saturated to start with which they are with a DSLR, how does one get color into them

Nice one Peter!. To recover the colors on the stars, select them with color selection > highlights, feather the selection anc copy/past as new layer, than reduce their curves to recover some "space" on the right part (high lights) and not having 255/255/255 (pure white) on all channels, than minimum filter (1 or 2 px), increase color saturation, gaussian blur (1 px) and voila', you have some color recovered.
Also to get star colour, you could take some shorter exposures and blend that stack in.
So if you take 10Min exposures then take some 2Min exposures.
It is like what you do with a mono camera.
