MDM Trouble Report for 2005 Apr 22

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

Problem(s) Encountered:
First, there is considerable difficulty with the set and guide
motions in the N-S direction.  The guide button has to be held
down for 10-15 seconds before it will move, most of the time.
It's usually more effective to set first, and then you can
guide in the same direction.

Furthermore, it seems that both the set and guide motions in
the N-S directions don't work at southerly declinations.

Finally, the guider focus hand paddle doesn't seem to be
working in either direction.  Fortunately, the guider
happened to be in good focus already.  After shutting down,
I moved the coarse adjustment of the motor to approximately 
the middle of its travel.  But when I hold down the fine
adjustment toggle switch for a long time, I still see no
motion along the scale in either direction.  It's as if there
were no power to the motor.  I don't know if this is related,
but I pulled out a little piece of crumpled scotch tape that
was sticking out from above the slide on which the motor
travels.  It didn't seem very important.
  
Tomorrow night, I will try to readjust the focus of the guider
very carefully with the coarse adjustment, but I don't know
what else I can test to diagnose this problem.
