Edit: Ok folks, after Al's reprocess and guidance with the tutorials he posted, I had another go at processing this one. I have attached it to this post. Although I do have photoshop, these days I tend to process all my images totally with pixinsight. PI doesn't have rope selection tools or the like because when you use these tools, you are manipulating the data it an unnatural way, meaning doing something to a certain structure rather than to all pixels at a particular brightness etc. (I am not criticizing anyone for using these tools, as to highlight some structures you need them). I still prefer Al's repro because he managed to bring the pinks out in the nebula's by using such tools. However I am trying my hand at staying true to the data bla bla bla, so decided not to use them. The attached reprocess is the closest I can come to Al's with my current knowledge using PI. I am sure that with more practice I will be able to get there, but for now this is it. I may have a go using PS later down the track.

Hi Rex,
you won't be able to get the image like mine unless
you do blurred masks in Photoshop of certain small & large areas.
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
