MDM Trouble Report for 2021 Feb 04

Telescope: 1.3m
Observer(s): Bhagya & Weil (Purdue)
Instrument: Templeton

Problem(s) Encountered:
Telescope errors occurred pointing at DEC > 74 degrees. The 
telescope would not slew from JSkyCalc even though the object was
east of the meridian and away from the West limit. As a result of
the slew error the telescope seemed to lose its encoder positions.
Telescope was then pointed to the zenith and the tip/tilt 
sensors were used to zero the telescope. At a later point in the
night the telescope slewed to DEC +73 but was not pointing 
at the correct field, slewing the telescope to lower DEC
found the correct field without needing to reset the telescope 
using the tip/tilt sensor. 

A second error occurred with guiding and blurred images. The guider
was over corrected in y-axis bouncing the star back and forth. 
It is possible this error was due to wind shake, since slewing
to a different part of the sky fixed the problem, however the 
wind speeds were low (~10mph) at the time.
