NOTES:

Seeing was about 3 arcsecond most of the tiime.  Could not see the ring-planet gap on Saturn.  The highlights of the brightest craters pop at Full Moon, like a string of beads across the disk. 

The libration also makes the limb interesting on the Terminator.  You can make out Mare Marginus by Mare Criseum, Neper, Mare Smythii, Ansgarius, Hecataeus and Humbolt with its central peaks.  The last is about the 4 o'clock spot on the rim.  RAW file, brightness, contrast, curves in PS CS2.
