MDM Trouble Report for 2013 May 05

Telescope: 2.4m
Observer(s): Halpern, Liu (Columbia)
Instrument: Modspec/Templeton

Problem(s) Encountered:
There is something wrong with the RA encoder. 
Even when resetting the encoders before
slewing to a new target, it will sometimes
lose pointing by the time it gets there,
necessitating use of the tilt meters.
This happened three times during the run, 
I think, including tonight.

On the previous night the coarse focus (motor mic)
of the guide camera slipped inward to the point where
it was not possible to focus.  Today, I manually pulled
it back to where I thought it should be centered, and
it is fine now.
