Park mount after failed meridian flip and hangup during imaging sequence was created by El Corazon

It does not happen often, but when it does, it is distressing: The scheduler is humming along, everything is working great, but then the meridian flip fails.
At that point, Ekos gives up, but unfortunately, the mount doesn't. It continues to track until it wraps the telescope around the pier or the tripod legs.

That happened to me again the other night. I wonder whether it would be possible to instruct the mount to park itself, if 2 retries at the meridian flip fail, and then restart the imaging schedule from there.

Another idiosyncracy: When I image a sequence manually including guiding, but then want to stop that sequence and start the scheduler for the rest of the night, the scheduler starts fine, will command focus, plate solve and align, but then it will hang when it is supposed to start the imaging sequence again. All it says is "Waiting".....

There is no way to get out of this without restarting Ekos.

Thanks for reporting!
@sterne-jaeger is reworking the meridian flip section, let's wait for the outcome.
About the sequence restart issue, is Scheduler waiting for guiding to restart? Or really waiting for capture to restart?

It seems to start guiding fine. It is just at the stage where now the exposure sequence should start again that it hangs and waits forever.
Log from the last session is attached. I think the problem happened around 21.13 pm, that's about the right time and that's what it looks like to me when I am looking at the logs.

Thanks for looking into this guys!

Eric, I retested this the other night. The problem only manifests itself if I image my target manually, i.e. not using the scheduler, before astronomical twilight allows the scheduler to become active (if twilight box is set), AND I then stop the exposure sequence before activating the scheduler. In that case, exposures will not restart and the scheduler will continue to hang at the exposure "Waiting" step.

If I select another exposure sequence from my list of .esq files, i.e. purge the aborted sequence, and then start the scheduler, it will proceed just fine.

It seems that the previous aborted sequence continues to hang around somewhere in memory and needs to be reset.

Small idiosyncracy one can live with, now that I know what to look out for.

Cheers

Thanks. So the issue seems to occur when the scheduler attempts to execute the same sequence file as is already loaded in the capture tab, correct?

That is correct. But I believe that is the case only if that file had been partially executed and then stopped. Once I purged it by pulling up another .esq file and the reloaded the first one, it was no longer causing a problem, even if loaded in the capture tab.
