MDM Observatory 2.4m Telescope Observer's Report for 2008 May 10

Observer(s): Statler & Sharma
Institution(s): Ohio University

Instrument: CCDS + Retrocam

Worked for 10 hours (all night)
Conditions were Non-Photometric most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Clouds all night.
   Beg: Seeing 1.5 arcsec, Patchy Clouds, Winds Light & Variable
   Mid: Seeing 1.5 arcsec, Patchy Clouds, Winds Calm
   End: Seeing 1.5 arcsec, Patchy Clouds, Winds Calm

Observing Summary:

Hazy all night long, and the fires still appeared to be burning 
a few miles south of us. Seeing values in the table above are
best guesses.
Used CCDS for spectroscopy of near-Earth asteroids. Had fun tracking
(including guiding by hand) an asteroid with proper motion of 
several arcsec per second. We could not specify tracking rate 
to high precision through TCS - the actual tracking rates seem 
to change in steps; e.g 15.009 arcsec per second seems equivalent
to 15.001. We didn't expect this, and were wondering if this is 
indeed a true feature of TCS.
