MDM Observatory 2.4m Telescope Observer's Report for 2001 May 26

Observer(s): Vestergaard
Institution(s): OSU

Instrument: CCDS

Worked for 8 hours (all night)
Conditions were Non-Photometric most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Clouds all night.
   Beg: Seeing ~2 arcsec, Cirrus, Winds Light & Variable, thin cir. @horizon
   Mid: Seeing ~3 arcsec, Cirrus, Winds Calm, cirrus widespread
   End: Seeing ~3 arcsec, Cirrus, Winds Calm, cirrus widespread

Observing Summary:

After the head electronics was recovered late afternoon, the
CCDS computers were brought to working order by kind help 
from Rick Pogge. Both the instrument and the telescope worked
fine all night with no problems at all.

Thanks to Bob for checking out the telescope, to Rick for
spending many hours during the day trying to fix the instrument
electronics, and to Bob, Jules, and Jerry Mason for checking
back with me as to the status.

One comment: The guider tv is harder to adjust now. It doesn't
respond well to adjustments in voltage and in particular will 
not turn off when the dial is turned down. Stars are still seen at 
the same level as before. It also takes a bit longer to shut itself
off when the finder mirror moves in and reflects the arc lamps. 
It can still be used, though. Is there a way to reset the voltage?
Turning the voltage box off and on again, does not solve the
problem (which might be obvious to those more knowledgable about
what might be the problem).
