I like the image Paul - as is. Colour & composition look spot on.
To be picky, the stars are a bit soft and a bit too large for the subject matter - and I mean a
bit. Are your Ha stars smaller? If so strengthen the contribution of the Ha stars. Some minor star reduction may make things pop more. Do you do any decon?
Cheers, Marcus
PS: just saw your last post - mostly Ha Lum - just ignore my picky comment
