MDM Observatory 1.3m Telescope Observer's Report for 2006 Apr 29

Observer(s): Halpern
Institution(s): Columbia

Instrument: Templeton Direct

Worked for 9.5 hours (all night)
Conditions were Photometric most of the night.
Problems were encountered, see the separate trouble report for details.

   Beg: Seeing 1.6 arcsec, Clear, Winds Calm
   Mid: Seeing 1.2 arcsec, Clear, Winds Calm
   End: Seeing 1.1 arcsec, Clear, Winds Calm

Observing Summary:

Good observing. Had to reset the dome encoder a couple of times.
After using this telescope for several years, I have the distinct
impression that there is some imbalance in the mirror suport that
makes the images triangular in some positions.  You can see it
when the seeing is good.
