Re:Scheduler didn't continue to next valid job

Hi,

I was trying to image 2 objects last night, the Horsehead Nebula, and then M51.  The switch should have occurred around midnight, as I had a 34 degree altitude limit.
The previous night I did M42 and then M51.  M42 job completed and then M51 continued around the same time.

The log file shows the scores calculated correctly, but the system was shutdown after the first job was interrupted instead of continuing to the valid 2nd job.

Any thoughts?
Thanks
David

Yes, this problem is more or less known and is a shortcoming of the current implementation of Scheduler, although it works like this by design. If you add a restriction such as an altitude limit and the job does not finish before the limit is attained, the Scheduler will reschedule that same job to the next opportunity and wait.

This is implemented that way because we considered how to build the preliminary plan based on restrictions, but most of the time we observe that this unintuitive reschedule discards many hours of exposure.

To avoid this situation, use the time interval on the right-hand panel instead. This forces you to calculate the time matching your altitude limit, but does not reschedule the job to the next night. Note that the time is actually a date+time, and must be adjusted when you load your schedule file.

You may also want to try the reschedule options at the bottom of the middle panel when jobs are aborted (note, aborted).

Thank you for the explanation and the tip to use the time limit. I'll use that instead instead of the altitude limit.

It would be a WONDERFUL addition if the ending date-time could be flexible enough to recognize "tomorrow" or "next day" as a stop date. This way the same schedule file could be used for many nights.
