I have had a recurring problem with my mount disconnecting or becoming unresponsive during imaging sessions with SGP. This issue used to happen constantly when I was using a different computer but seemed to go away briefly when I switched to a new one. Now it is happening again.
Thanks to a stretch of good weather, I’ve had my rig outside for the past two nights. Two nights ago, I had no problems. This morning, however, when I checked my imaging computer, I was greeted by an error message saying the Celestron mount server stopped working or responding (just after I went to bed, naturally.) I regret that I did not have the presence of mind to take a screen shot of the error.
I think the logs indicate the mount stopped responding around 12:25 AM:
