Observing Summary:

Observed from sunset to 9:00pm, then humidity went up above 
limits, and I had to close the dome. Re-opened just before 
1:00am when humidity levels went back down. There was some 
condensation on the dewar window, but it cleared up after a 
few exposures. Things went OK after that. Tracked two candidate 
transit systems until morning twilight.
