OK, that explains it. I am still running 2.9.6 on the Zotac I used last night. That run went fine, but at the end I found another problem: I had checked 'Repeat schedule 2 more times' instead of 'Sequence completion', because I saved the images to a folder that already contained images from a prior run and I did not want the sequence to stop once it had reached the maximum number of exposures specified in the M27.esq file. As M27 crossed the minimum specified altitude (43 degrees) the scheduler stopped the sequence and searched for the next job, which was again M27 but for the next night.
But instead of shutting down, the scheduler merely went to sleep. It did NOT park the mount, instead it continued to guide until I manually shut down the mount.

This is another potential unintended consequence of rescheduling: Failure to park the mount and shutting down at twilight. Twilight should override rescheduling and force parking and shutdown.
Here again a link to the log file from last night.

I hope it helps. Thanks for the great work, Eric! I collected a full run of 104 x 180s exposures last night, Failure to shutdown and park was the only hitch this time.
