I made this observation of Mars this morning with the CM at ~19°--close to the other observations posted by Jim and Bruce the past few days. Seeing was good but not great. All the albedo features seen were very low contrast with and without filters. As the seeing improved, my corrector plate dewed up. That may be why I was unable to detect Meridiani Sinus which is the dull area close to the terminator. I did a star check at 500x and found my collimation is a little off--that would also affect the contrast. There could still be a fair amount of dust in the Martian atmosphere, too.
The blue morning clouds and blue NPH were the most striking details.
