Worked for 9 hours (all night)
Conditions were Non-Photometric most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Beg: Seeing 1.5 arcsec, Cirrus, Winds Calm
   Mid: Seeing 1.1 arcsec, Cirrus, Winds Calm

Observing Summary:

Good seeing but highly variable transparency despite relatively 
clear skies. Need to check OSMOS' interior for possible 
foreign material blocking light.
Image quality looks much improved with Airy ring clearly visible
around brighter stars. The guider clicked off twice for no 
apparent reason.
