MDM Trouble Report for 2013 Apr 23

Telescope: 2.4m
Observer(s): Jenna M. Nugent (U. of Oklahoma)
Instrument: OSMOS, R4K

Problem(s) Encountered:
Last night I had trouble getting the guide star in focus. I attributed
it to gusty winds. However, tonight I had the same problem and it was 
not very windy. I tried focusing out for a while then in for some time. 
Focusing out always made it worse, whereas focusing in never 
improved the focus much. After trying this for a while, I realized the 
guider's pointing was off. I tried setting it to origin, and that helped at
least getting the guide star more in the FOV. The focus was somewhat better
after this. The pointing issue could be due to my script, which
dithers after readout of the last image. Sometimes during readout of 
the last image in a field, I would stop tracking with the guider. Perhaps the 
guider dithering after this made it lose pointing.
The weather screen froze, but still updated the wind speed and a few other 
things.
