Thanks Raoul - I tried to retain the color values from the RGB composite as much as I could when adding in the luminance image. There was a slight bluish cast to the albedo features which does seem to carry through in the eyepiece view through my scope.

Excellent image, Alan!

I like your way of not overprocessing details... how did you go about the colors? Did you

calibrate your filters/camera to reproduce daylight colors correctly, or did you adjust the

colors more freely to reproduce an image similar to what Mars looked like in the scope?

Just curious, as I have a number of images waiting to be processed... hopefully soon.

Best,

raoul
