MDM Observatory 1.3m Telescope Observing Report for 2008 Dec 29

Observer(s): Schroeder
Institution(s): Columbia

Instrument: CCDS

Worked for 13 hours (all night)
Conditions were Photometric most of the night.
Problems were encountered, see the separate trouble report for details.

Seeing and Weather:
   Beg: Seeing 1.3 arcsec, Clear, Winds Light & Variable
   Mid: Seeing 1.0 arcsec, Clear, Winds Light & Variable
   End: Seeing 1.0 arcsec, Clear, Winds Light & Variable

Observing Summary:

Great seeing, good weather.

There seems to be some issue with the tracking.

Turning off the guide camera for five minutes resulted in a drift of
about 10 pixels on the guide camera monitor as though the telescope
were drifting to the east. Additionally, when changing the focus, the
telescope moves enough North or South to lose the guide star.
