NGC281Ha/RGB

Hi all,

I've had a chance to process the RGB data on this to go along with the Ha I posted earlier,I have to say I'm not real pleased with the outcome I seem to keep coming to.The RGB was aquired under a near full moon and is just not as good as I need it to be,pretty weak considering the amount of time in it sad

This is now 40x600s Ha
25x240s Red
25x270s Green
20x360s Blue

I usually shoot equal exposure times but thought I would try something different here,maybe if not for the moon the RGB would have been better.

Here is what I ended up with,so far!
Can't seem to get a good Red saturation no matter how I blend the Ha in,unless I barely use it.

Hello Jason,

try to use as luminance a blend of red and h-alpha (try different percentages: for me 65% h-alpha and 35% red worked fine on my only experiment in this matter). This should take care of the salmon color of the nebula and also should give some color to your stars, which inevitably loose it in this kind of color combination.
I read this in the Zone Processing: the last chapter is by R. Croman and is specifically dedicated to mixing emission line and natural colors.

Ciao
