MDM Trouble Report for 2010 Dec 15

Telescope: 1.3m
Observer(s): Shields, van Saders (Ohio University, OSU)
Instrument: CCDS

Problem(s) Encountered:
Problems arose while attempting to move the dome manually 
during the night.  To mitigate windshake, we raised the dropout
shutter after sending the dome home with the TCS, and subsequently
allowing the computer to take it back to follow the telescope.
Later we attempted to lower the dropout by first putting the
dome in manual mode with the switch in the dome (as advised by
Bob), and rotating from the dome panel.  The dome started to 
rotate as desired, then stopped responding to the dome switch
and rotated back to following the telescope.  At this point the
dome was unresponsive to the manual switch even though the 
panel was set to manual mode.  We finally turned off the
telescope tracking, at which point the dome became responsive
to the manual switch and we were able to rotate home and lower
the dropout shutter.

After returning the panel switch to auto mode, we attempted to
put the dome back to centering mode with the TCS button which
generated an error message  socket not connected.   After
some investigation we found that the rslit process was not
running, so we turned off the telescope control and restarted.
We completed one further observation at the current telescope
position and attempted to use jskycalc to slew to the next
object, which failed with an error message (yellow) on the
jskycalc panel.   We subsequently restarted jskycalc and 
succeeded in slewing but were unable to find our next source
and ended up going to the zenith to rezero the pointing from
the TCS panel.

Subsequent attempts to use jskycalc to slew the telescope 
failed with a red error message, even after restarting the
program.  For the remainder of the night we slewed the
telescope from the telescope control panel.

Summary: rotating dome from the panel in manual mode did
not work as expected, telescope control failed, and upon
restart we have been unable to get jskycalc to interact
properly with the TCS.
