Lovely image Paul. I always struggled in my film days to bring out the lovely blue Running Man nebula.
Sweet image Paul!

At any chance.. did you try out yet GradientXTerminator? It can help remove gradient to neutralize the background.
I'll second that! Very simple to use (the 'simple' part really appealed to me

). Hope you don't mind Paul but I did a quick example of how it can work in only a few seconds (I also 'bumped up' the Ha a wee bit as well).

Processing astro images is a real minefield nowadays. Gone are the days of sending a film to Truprint and getting your shots back sliced in half (somehow the free, golfball grain film that they would send you never quite seemed to compensate)!!!
