MDM Trouble Report for 2018 Oct 18

Telescope: 1.3m
Observer(s): Jules Halpern (Columbia)
Instrument: Templeton

Problem(s) Encountered:
Trouble started when I slewed to HA=-6, dec=+53.  The telescope
almost got there, but stopped short a few minutes of time with
an error.  I waited for a while, and started observing at HA=-5.5.
But many times the tracking stopped after a couple of minutes. 
The telescope apparently 'prefers not' to observe at such a 
position, even though it clearly can.  After a while another
problem appeared: a rapid E-W oscillation, much faster than the
guide camera could resolve.  This was seen many years ago,
and was traced to a ~10 Hz oscillator in the system.  Eventually
this problem also went away, and the telescope behaved very well
at small hour angles.
