Hi Group,
My session started around 6:36 last night and completed its third sub at 7:22. I suspect clouds rolled in shortly thereafter since the PHD2 logviewer shows the beginning (but not completion) of a fourth sub.
I checked the OBS around 9:30 and found iOptron CEM120 had not “flipped” at the designated time (approx. 8:25pm) and the mount had continued tracking. It is set to stop tracking at 7 degrees past meridian (max limit is 14 degrees), but appears not to have. SGPro was set to pier flip at 5 minutes past meridian (approx. 1.25 degrees). When I shut the system down, the mount was up against a hard stop. Sending the unit back to its Zero position showed that Zero was off as well as the Park position.
However there was no problem re-establishing both correct positions.
My guess is that the clouds moved in and PHD2 lost its guide star, and SGPro did not shut the system down as a consequence. I could be wrong here because my log interpreting skills are woeful at best.
I would appreciate if you could look at the material in the DropBox attachment and give me your thoughts on what may have happened and if there is a continuing risk.
Thanks,
Mark
