MDM Trouble Report for 2017 Oct 16

Telescope: 2.4m
Observer(s): Fesen and Weil (Dartmouth)
Instrument: Echelle Direct

Problem(s) Encountered:
We experienced problems guiding on targets. Guider would freeze
and stop guiding and occasionally the guide star would rapidly
move. We fixed the problem by changing the guide camera speed
to 1MHz, exposure time to 1sec and aggressiveness to 6 in both
x and y. The freezing of the guider may be solved by refreshing
the guiding every half hour or so. 

The guiding accuracy with the new setting was quite good.
