Observing Summary:

Humidity has been rising throughout the night. High clouds toward sunrise. The  camera not responding  problem seemed to crop up when sending too many commands from CCDOPS. 
The guider seems to be losing power briefly. The guider monitor usually loses image clarity and the counts that keep guiding engaged drop which causes some shaking in the guiding.
