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.

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.
