MDM Trouble Report for 2017 Jan 04

Telescope: 2.4m
Observer(s): Simonian (OSU)
Instrument: OSMOSB4k

Problem(s) Encountered:
One of the major issues that popped up during the night was that 
after I would slew to an object, I wouldn't be able to find the 
chosen guide star in the guider. This is despite there being 
clear skies. However, a workaround would be to slew to the 
nearest bright star and then slew back, after which the star 
would be where it is expected to be. Shortly after, I noticed if 
I left a star untracked in the guider, it would slowly drift to 
the left side of the screen, as if the telescope itself was 
drifting faster than it should. In an effort to reboot the 
tracking system, I turned off the drives, auto guider, and 
tracker, and then turned them back on. That did not seem to 
immediately solve the problem. However, I found that a workaround 
would be to send the current target's position to the TCS
 whenever I needed to find the guide star again, and the star 
would then appear. If the telescope was in motion, such as 
with the hand paddle, the drifting did not appear to take place.
Eventually it stopped.
