I'm giving up on this now - tried about a zillion reprocesses of the RGB I got for my Elephant Trunk Neb image down at Les Granges.. this is about the best but I'm still not happy. I think I probably didn't get enough colour data to go with the Ha data that I got... :-( I've also put Ha data underneath...
Anyway, here it is....
Cheers, John.

Looks good to me. Lots of detail along that thin section of the 'trunk' and good focus. Nice image.
Nice detail.
Just out of interest, how are you adding the Luminance data?
Are you converting the Image to a LAB, and then adding the Luminance layer, and converting back to RGB?
Or do you do it a completly different way?
looks good to me...
Cheers everyone - I may try saturating it a little more - The hardest thing was trying to keep the 'horrendous' blue halo's at bay....
Mac - I use a couple of methods for adding the L as follows:
1. Process the L & RGB separately & then convert the L (or Ha) to RGB mode & then paste the colour image on top as a new layer then change the blend mode from Normal to 'colour'... or
2. Process the RGB image & then copy & Paste the L layer on top & change the blend mode from Normal to 'Luminance'.. (this is what Chris does)
HTH, Cheers, John
John, I've just posted my Halo removal method in the Technical area. It's not a perfect solution in all cases and is a bit tedious but if it helps then all well and good.
Cheers
