Decided to go back to this image and try out Mark's star colour treatment on it.
This is my Original process:

This is the same image given the Mark's Arcsinh colour star colour retention process, and I think it's improved the whole image colour at the same time.

I can see myself going back through lots of images improving them now.
Thanks Mark.

The new version is really nice Carole. Marks a clever old stick.
Thanks Duncan, yes he certainly is and generous to share his expertise.
I don't know why the first time around I was getting brown bits round the nebula where blue bits ought to be.
Carole
That's come out really well!
Mark

Carole
