MDM Trouble Report for 2003 Dec 27

Telescope: 2.4m
Observer(s): Brogt (Columbia)
Instrument: 8k

Problem(s) Encountered:
Filter wheel keeps timing out when changing filter. Needs to
be done several times before the filter reaches its position.
Also, screeching metallic noises can be heard when changing
filters.

More importantly, the RA tracker is slipping. Long exposures
will almost certainly fail. It is unpredictable when this
happens. It may happen every 90 seconds or it may go well for
an hour. No telling.
