This is a work in progress. There are loads more videos to process & I feel it is worth wringing the neck out of this set! Seeing was steady enough to allow considerable detail to be seen on the tiny (11.6 arc sec) disc.
2108 UT. Celestron CPC 1100, 3x teleconverter, Astronomik RGB colour seperation filters, Imaging Source DMK21AU618 camera. 1.5x resize of RGB composite with red used for luminance.
The dark band just inside the right limb is probably a diffraction artifact ... but the bright patch on the extreme limb is real, Nix Olympica was just rotating round the limb (shows up much better in shots made earlier) and must have had a large orographic cloud formation over it.
Edit: A different process from the same capture - gives a prettier picture but some of the detail is harder to make out.
Edit: I think this is the finished product - unless I can find a few more tricks ...
Note the bright cloud on the sunlit limb over Nix Olympica and the haze near the equator in the "morning" hemisphere. The slightly lighter patch dead centre is Elysium.
