Last week I had a night with decent seeing conditions (albeit very light-polluted), clear skies, and good guiding (average RMS of 0.5", with RA = 0.32" and DEC = 0.38"). I guided for 4 second intervals. I have the ASIAir set to stop tracking at 5 minutes prior to Meridian Flip and resume 5 minutes after. I have the mount set to stop tracking at 0 degrees prior to flip to guarantee the ASIAir stops first.
I got 9 good shots prior to the meridian flip. The flip went well, and after recalibrating and settling, the tracking resumed. I went inside for a few minutes. When I came back out, the mount was stopped, and pointed in a random direction. I sent the mount to the home via the hand controller, and shut everything down. I then resumed the plan, and got two hours of normal tracking.
According to the log (attached), during the time I was inside, the mount made 5 attempts, then stopped. because it couldn't find the guide star.
This is not the first time this has happened. In fact, the exception is that it doesn't. It has happened to me with the ASIAir Pro on a Skywatcher EQM-35 pro mount, later on the same mount with the ASIAir Plus, and this last time with an iOptron HEM44EC mount.
I'd really appreciate any help, given this costs me at least an hour of imaging time the majority of my sessions.
Thank you.
