MDM Trouble Report for 2017 Jun 18

Telescope: 2.4m
Observer(s): Ryan Chornock (Ohio University)
Instrument: OSMOS/B

Problem(s) Encountered:
The telescope pointing definitely deteriorated over the run.  Big moves across the sky would sometimes have shifts of a few arcminutes in pointing, as sometimes happens with the 2.4m.  By the morning hours of last night, I had one object that did not fall within the OSMOS field of view, even after sending it to center field and reading out the full 4K field.  After trying to find a few bright stars, I went to zenith and reset using the tilt sensors.  The pointing was off by a few minutes of time.  After zeroing at zenith, I was able to find a bright star, reset the RA/Dec encoders and get on with my night.  About 45 minutes lost.
