My first HaRGB attempt - Eta for a change

Dave, hard to tell from these tiny files but I like the middle one the best, the detail around the keyhole is excellent and looks quite natural.

Nice Ha blending there too

Thanks Mike - the middle one is the original one I posted. My favourite too.

Problem is I just can't replicate that effect when I try to reprocess it!

The exposure details are:
QSI583 at -15 degrees:
Ha:R:G:B - 90:30:30:30 (10min subs for Ha, 3min subs for RBG binned 2x2)

Just fiddled in PS - blended the Ha in as a luminosity layer plus a few other adjustments, sharpening, etc... Bring on the Astro-Imaging Conference!

Higher resolution version available here

Ha high res version here

Thanks for looking,

Hi David,
It's amazing how great Ha is in pulling out fine detail. Just spectacular.
I am wondering about the slight violet haze around stars - is it CA or a touch too much on the sharpening pedal? Great composition too, by the way!!

I keep pages of notes in Excel David, for different techniques and applications. You can usually remember something is possible, but trying to remember every little intracacy is too much for my little mind a lot of the time
If you jot something down everytime you read about a worthwhile technique its amazing how they grow over time, and helps you look back at how your processing changes as you learn. My 2c anyway.
