MDM Observatory 1.3m Telescope Observing Report for 2009 Mar 11

Observer(s): John Thorstensen
Institution(s): Dartmouth

Instrument: templeton + buckeye fw

Worked for 8 hours (most of the night)
Conditions were Mixed most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Clouds from 10 pm until 1 am.
   Beg: Seeing 1+ arcsec, Clear, Winds Light & Variable
   Mid: Seeing 3 arcsec, Cirrus, Winds Moderate
   End: Seeing 2 arcsec, Clear, Winds Light & Variable

Observing Summary:

Clear at the start and end, and high clouds in the middle. Did
timeseries work unattended.  In the middle, when the weather was
poor, I experimented with the 1.3m offset guide probe to be sure
I had the scale right; it's close to 0.08397 arcsec per motor
step, quite different from the 1.3m manual.  As a guess, this
number has 2.5 actual sig figs.

Drive chattered for a half-second on evening startup, and I didn't
see any clear evidence of preload issues this evening, but I 
wasn't watching closely.
