Hi all,

I took some color data and some more luminance on my M81 shot. I still can't seem to get the color in the stars that I'm looking for.

This is 300:180:180:180 LRGB all 5 min subs binned 1x1
AP 130mm F8.35
ST-10XME CFW8a with Astrodons
G11 Gemini level 4
TCF-S
shot using CCD commander.

cheers,

Jeff

Stars aren't saturated are they? That could also do it.

Tony Hallas has made a 3 DVD set of how to process deep sky images. How to get good star colors is discussed, among a miriad of other advanced techniques and tricks. We'll be selling this set on the AP web site soon, if you're interested. Probably be up next week.
