Freds version
is pretty speccy huh? but you have some excellent detail there David, remines me of a close up of
NGC 604 in M33
Might be nice to collect some colour data to incorporate though? You could blend the narrowband data with the colour data, could be a beauty
It can really work well, I was forced to do it when I was imaging under severe light pollution and poor seeing - for example, these are both HaOIIIRGB blends
Orion Nebula
Eta Carina
I would blend the OIII data with the blue and green and the Ha with the red and the Blue then use a hybrid Lum made with The OIII and Ha...then a bit of fiddling but it works
