As seeing improved (but breeze started to pick up) I decided to finish the imaging session with couple of non-filtered captures of Saturn as that allowed high frame rate (30fps or so) even at Martian-esque (large) scale. Having the luxury to be able to pick from nearly 12000 frames resulted in a "as good as it gets in a C11" luminance image, IMHO. But color data captured earlier was unfortunately done at slightly different angle and scale (as I was observing using -er-
eyes in the meantime

) so matching proved nearly impossible.
After a
lot of fiddling in Photoshop I finally managed to align color data to the pure luminance data. Luckily a perfect match is not quite needed as color channel doesn't really hold that much information, so crude mouse driven rotation and pixel-level (not sub-pixel) alignment had to suffice.
Color might be a bit rich for my taste but I actually liked what I saw in this forum before, so here it is.
