MDM Trouble Report for 2004 Nov 11

Telescope: 2.4m
Observer(s): patrick cseresnjes (columbia)
Instrument: 8K camera

Problem(s) Encountered:
When the telescope pointed at an airmass > 1.8, the 2nd 
controller (slave) of the 8K camera powered off. To bring it 
back, I had to switch off the controllers (both master and 
slave), detach the detcom window, switch on the controllers, 
and launch a new detcom session. After that, the camera would 
work as long as the target remained at an airmass < 1.8, 
otherwise, the same problem occured.

Therefore, our main target (M31) could no more be observed once
it reached the airmass of 1.8. This is not too big a loss since 
M31 was going to be unobservable anyway, but it would have been 
nice to take advantage of the excellent observing conditions a 
bit longer.
