MDM Observatory 2.4m Telescope Observing Report for 2018 Sep 12

Observer(s): Weil
Institution(s): Dartmouth

Instrument: OSMOS/B

Worked for 9 hours (all night)
Conditions were Photometric most of the night.
Problems were encountered, see the separate trouble report for details.

Seeing and Weather:
   Beg: Clear, Winds Calm
   Mid: Clear, Winds Calm
   End: Clear, Winds Calm

Observing Summary:

I ran into problems with the Automatic Focus Temperature
Compensation system. The focus values for the telescope
do not agree with the temperature changes when the system is 
enabled or after it was disabled (details are in trouble report).
This caused problems with images being out of focus during the 
night.
