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.

Complete SUMMARY part: With enabled Meridian Flip and Scheduler->Alignment-> "Verify captured image position" + "Reset pipeline if delta exceeds" when re-alignment triggers together with meridian flip, meridian flip gets interrupted and aborted by re-alignment, causing MF not occurring, job not resume, and mount eventually hitting HA limit and/or hardware limit
