SUMMARY
With enabled Meridian Flip and Scheduler->Alignment-> "Verify captured image
position" + "Reset pipeline if delta exceeds"
STEPS TO REPRODUCE
1. Enable meridian flip
2. Set Scheduler->Alignment->"Verify captured image position every" 1 "frames"
3. Set Scheduler->Alignment->"Reset pipeline if verified image delta exceeds"
0.1 "arcminutes" (very small on purpose to ensure it triggers together with
meridian flip); use e.g. dithering to ensure image drift exceeds delta
4. (optional) Set HA limit
5. Start job that for target that will go past meridian mid-job, triggering MF
OBSERVED RESULT
Meridian flip fires up, mount status changes to "Slewing", but MF gets
immediately aborted due to re-alignment triggered by captured frame being too
far from target. Alignment finishes, but MF doesn't happen and job never
resumes, eventually mount reaches max HA limit and/or hardware HA limit and
freezes.
EXPECTED RESULT
Target drift check and re-alignment are skipped when MF is pending/running.
