I presume this is Ha added to the red channel?
Looking very good detail Roger, I think it is a but too red and dark, but otherwise its a nice bit of processing.
Carole
I'd agree with Carole on those comments. I'd also add 20-30% to green channel because of the Hydrogen beta component but only if you can isolate the nebula and process separately.
