Job sequencer / auto guide problems

I think I found an explanation what happens. It seems like the internal guider recovers itself after the slew and starts guiding faster than the scheduler:

And here in comparison a sequence from my log file where everything works fine:

Does anybody have experience with the internal guider?

The issue was in the scheduler. I fixed it in this commit .

This is great. Thank you.

I don't know how to work with the Git link you provided. How long before it makes the nightly release if it's not there already? And how can we know when this or any other fix moves from nightly to stable?

It's in nightly already and is in stable with today's v3.2.3 release... but we didn't officially announce v3.2.3 since we have issues with the Windows build so hopefully tomorrow we'll announce it.

Using both the nightly (2019-05-30 13:10:05) and stable (2019-05-30 9:48:47) I have the same problems - no change in behavior. Guiding fails to re-calibrate on mosaic panel changes and focus is not called on either panel changes or meridian flip. Log attached...

Hi Viejo,
I did a similar test. For me it seems this looks like a problem with the internal guider. After slewing it seems like it does not select a new star. But I am neither really familiar with the internal guider nor do I really have experience with the guiding simulator.

I will do a check with PHD2 with simulators so that I can help you setting it up.

Hi Viejo,
it seems like I stepped into a similar problem this night. I had the scope already positioned to the target and PHD2 guiding was running. When I started the schedule with this target, the mount did only slew a tiny bit leaving PHD2 guiding - but interestingly it slewed enough so that there was no star any more. PHD2 reported "star lost", but did not terminate or restart the guiding.

Anyway, it seems like - in some situations at least - slewing does not automatically terminate guiding. I'll take a closer look...

This was reported fixed a month ago but it's not fixed. The problem isn't just with the mosaic jobs. The only time the scheduler behaves correctly is when it detects a change in pier side, a crossing of the meridian. I set up a job sequence with 2 objects on the rising side of the meridian, then 2 on the setting side and then 2 more on the rising side. When switching to a job on the same side of the meridian, it behaves as if it still has the guide star when in fact it's many degrees away. Switching to a job on the opposite side, it recognizes the need to recalibrate and behaves correctly.

It should be a simple fix to have it set the recalibrate flag when it detects any SLEW, not just a meridian change.

Attached is a log. I edited out a bunch of focuser commands that are irrelevant.

Is PHD2 configured to abort when the mount moves? This needs to be configured, kstars does not abort guiding when slewing. If you are not using pulse guiding, it might be the case that you need to set your mount as aux mount in PHD2 so that it recognizes slewing.

"...kstars does not abort guiding when slewing."

YES! That's exactly my point. It should, it's broken and it should be a rather trivial problem to fix.

There are probably two things that need fixing in the context of guiding:
- Proper stop of the Guide module when moving the mount (slewing, flipping, aligning...). As mentioned PHD2 is supposed to detect the movement and stop guiding by itself, but that is only a safeguard.
- Proper calibration reset of PHD2 when the Ekos option requiring to clear when starting a new job is set.
