MDM Observatory 1.3m Telescope Observer's Report for 2001 Oct 24

Observer(s): Hammell
Institution(s): Dartmouth

Instrument: ONIS

Worked for 11 hours (all night)
Conditions were Non-Photometric most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Beg: Seeing 1.3 arcsec, Clear, Winds Calm
   Mid: Seeing 1.8 arcsec, Clear, Winds Calm
   End: Seeing 2.0 arcsec, Fog/Low Clouds, Winds Calm

Observing Summary:

Having a problem getting the pointing to stay set.  
If I move by more than about 30 arcminutes after setting the coords, 
I'll find I'm off by at least 1 arcminute by the time I get where I'm going.
Assume this is due to the weight of ONIS, but don't remember having this problem 
before (last year).
