I know that is not scientifically correct but it does give a more pleasing image.
I started by drawing a mask as a ring around the galaxy.
I could see from other images posted that there you would find all the red nebulas & blue areas.
I then boosted it in LAB mode just for those areas & the colours popped.
Further refinement of the mask using the paint brush at different strengths then highlighted only the areas I wanted.
This mask was then blurred & feathered - & the opacity altered.
I had to do this many times & even mask just many tiny areas in the same way
to get the final result here:

Maybe I actually overcooked it & perhaps the previous version with
a noise reduction mask on the background would be better?

Should I fix that version?

cheers

Hi Al, yeah I do realise that's what I will have to do to achieve similar results as you. I will probably have a go at it with photoshop one of these days. I am pretty happy with the data as you said, so i want to get the most out of it.
