MDM Trouble Report for 2003 Nov 22

Telescope: 1.3m
Observer(s): Onken (OSU)
Instrument: CCDS

Problem(s) Encountered:
Two problems:

1. the finder mirror wouldn't respond to the switch on the 
silver box in the control room and was stuck in the 'in'
position. The fuse looked okay, although I think I may have
damaged it when I pulled it out later to double-check. Bob
talked me through how to manually move the finder mirror out
of the way, and I just didn't take any lamp spectra until the
end of the night.

2. later in the night, I noticed that my guide star was often
being lost, and always in the same direction (the telescope was
too far to the East). After playing with a number of the 
TVGuider parameters, I came to the conclusion that the guider
wasn't doing anything at all. It seemed to be reading correctly,
but there weren't any of the usual noises coming from the dome
to indicate an adjustment to the telescope position at the end
of each guider integration period. I tried exiting out of the
TVGuider program and restarting it, restarting the program with
the initialization flag, and rebooting the guider computer. 
Nothing helped, so I just periodically used the hand paddle to 
recenter the guide star (almost always just moving to the West,
I suppose because of a slight mis-match between the telescope's
tracking rate and the sky-turning rate).
