Ops Comments	none

TO Comments	Much delay in stacking due to various TCS/tracker problems. Couldn't get to load then couldn't clear the fault then forgot DMI part I didn't know about. Jim did a 21-point test. Did see the geosynchronous satellite tonight! Ran many tracks; finally able to conquer coma and focus by the last one.

RA Comments	Found most bright stars, but focus was extremely difficult.
