Ash... those pics of Jupiter are very good.
I've just started imaging with my C8 (which needs a clean) and SPC900 NC as well and my pics are not as good as that.
I'm using a C8 and 2X TV Barlow on an old old EQ5 driven with a Gotostar system. The Gotostar system is ok it's...just my old !+?0D% mount that is causing heartache. Also the C8 focuser is causing heartache..I need a cheap SCT crayford....any ideas on this?
Anyway I'm using K3CCD capture and Registax. I've just toyed with Astraimage today ...very nice.
Anyway if I could obtain images like yours I'd be pretty content...for awhile at least

.
Attached are some of my efforts in the last week.
Oh... one last thing...blue light is of such a wavelength that it suffers from "
Rayleigh Scattering" in the atmosphere..but you already knew that

.
I wanted to ask how you archived RGB imaging with the software? Did you just shut down the other channels? Excuse my nobishish.
