Re: [APML] High Res NGC 2841



Thanks Bobby and Sean. Yes there's some noise in the image
but I think its also accentuated by the "knotty" spiral arms of
this galaxy. I may give "grain surgery" a try but I'm afraid of losing
any fine detail. I was able to get the color to an acceptable level
by doing my "double dip" ( named after the famous Seinfeld episode <G>)
technique in which I used my first LRGB at 50% opacity as the new
RGB. This helped alot to bring up the S/N of the RGB data.
