MDM Trouble Report for 2018 Apr 07

Telescope: 2.4m
Observer(s): Hodges-Kluck, Hillig (Michigan)
Instrument: OSMOS/B

Problem(s) Encountered:
The telescope focus slipped over time. For almost all of the 
night we were pointed at the same target, and the focus value 
changed from our best initial value of 6350 to either lower or 
higher values, with a change of about 20 units per half hour. 
We used the focus button on the hand paddle to correct it every
so often. When we slewed back to zenith at the end of the night, 
the focus changed by 40 units. 

Without pointing to more targets the nature of the change is not
clear. We will keep an eye on it tomorrow.

Also, sometimes the dome does not track the telescope or go home
when told to do so, but after a manual 'kick' from the hand
paddle of several degrees it realizes what it is supposed to 
do and works fine thereafter.
