Observing Summary:

Productive night.  Had problems with the CCDS acquisition camera and control
system.  After moving from the east to a target 1h17m west at +5 deg communication
with the camera was lost.  I slewed to zenith so I could safely reach the camera.
After several restarts of the computer it failed to come back.  I then cycled the 
power to the camera on the instrument and restarted again.  THis time it came back.
I then slewed back to the west target and it failed again.  Went back to zenith and
checked all the connections.  Restarted and it appeared to work but after one 
iteration I got a  shutter error  and it stopped.  Talked to Eric.  Recycled power 
to the camera yet again and operation resumed.  No problems the rest of
the night.  Lost a little time from the problem.
