All, After 2-3 months of error free operation there was a glitch last night when for some reason there was a lost communication between CCD autopilot and the guider. This was the error message reported in the CCDAP log: Guider state -Idle- not reported after 4 guide exposure cycles of 3.0 sec. each. 03:08:10 Guider reported state: 10 03:08:11 SGC1 CCDSoft2XAdaptor.CCDSoft5Camera.1:, A Camera command is already in progress. Error = 120. I believe there was also an entry in the SBIG debug log which can be downloaded here: https://drive.google.com/file/d/0B_eg3ifhhPXaYklUM1o5VW9pUm8/view?usp=sharing Thanks Dave
