Description Jon Dalrymple 2024-11-03 05:08:10 UTC
SUMMARY
If I have a sequence that consists of a set of flat frames followed by light frames, and the flat frames require the mount to reposition (i.e. "park mount" or "goto wall" selected under Calibration Options), the scheduler doesn't know that the mount would need to be re-aligned after the flat frames are taken.

My use case is like this: I like the scheduler to slew the mount to the target, and then allow me to manually rotate the camera to match a required position angle. However the rotation means new flat frames need to be taken (especially if I'm scheduling multiple targets at different rotations). At the beginning of the sequence I need to the mount to slew to a position so I can coordinate the flat frames. After this is over, the capture sequence starts immediately, as opposed to repeating the target alignment (now with the correct PA).

STEPS TO REPRODUCE
1. Create a scheduler job that uses a sequence that requires flat frames before light frames. Check "park mount" or "goto wall" under Calibration Options.
2. Start the scheduler job.
3. After flat frames are taken, the light frames are immediately taken without slewing the mount back to the target.

OBSERVED RESULT
Light frames are taken with the telescope not aimed at the target.

EXPECTED RESULT
Scheduler should know that after a mount slew is performed to gather calibration frames, a re-alignment is needed before light frames can be taken.

SOFTWARE/OS VERSIONS
Armbian 24.5.1 Jammy
Kstars 3.7.3

ADDITIONAL INFORMATION
A workaround is that Kstars/Ekos can detect that the target is misaligned after the first light frame, triggering the mount to slew and realign.
