Great result H!! And welcome to the club!
You should be very pleased with that, it's tricky to do an effective HA blend and avoiding the salmon colours.
You definitely need to display a higher res version though ... full res would be nice!
I want to see PIXELS!
The colour looks spot on to me but I'm suspecting you can tease out some more depth of neb from your HA (?) Did you blend some HA into your RED channel?
Cheers, Marcus
