MDM Trouble Report for 2005 Apr 11

Telescope: 2.4m
Observer(s): Moore & Frank, Morgan (OU & OSU)
Instrument: Modspec + Wilbur

Problem(s) Encountered:
Guider problems :

Sometimes changing the gain did have NO effect on image in slit 
(even turning gain to zero and waiting for a long time, the sources 
inexplicably were still present !).
Moving the telescope,the guider focus changed severely.
The TV screen has a slit image 'burned in' - which was quite confusing 
when the gain started acting up as we could not see the real slit
position very well anymore. 

--> some of the problems might be related to the rapidly changing 
weather conditions, but certainly not all of them.
