Job sequencer / auto guide problems

Hi Wolfgang -

Thanks for your quick reply. Yes, that's the right log. I live in one of the foggiest places in the US and only have limited time to observe. I'm running sims to get all the kinks out so I don't waste valuable observing time trying to figure things out while shivering in the dark.

The problem persists. When changing frames on a mosaic, the guider goes straight back to auto-guide without grabbing a new image and finding a new guide star. However if it does an automatic meridian flip, it detects that the pier side has changed and goes all the way back to find a new star and re-calibrate. Today I'll try to run a mosaic on an object at the meridian that requires a flip in the middle and send you that log so we can see it it shows any difference.

The remember-job-progress switch fixed the other problem, thanks.

Do I get it right, you are using the internal guider, right? Maybe you should give PHD2 a try, it works well with EKOS.

Yes, I'm using the EKOS guider. I was trying to keep everything in one unified package. I guess I'll have to install PHD2 and learn it. Do you know if it will run properly in the simulator?

In any case, I think this remains a bug in EKOS that should be looked into.

Yes, you need to install PHD2 - and yes, it has a learning curve. There is a simulator included in PHD2 so that you can run it standalone.

I guess your problem is a bug. I will take a closer look, but this module is new for me, since I use PHD2.

Please note that you can also use the INDI simulator guider in phd2 and the INDI mount for a more realistic test than the phd2 simulator

Hi Wolfgang - I've re-run the simulation of a 2x2 mosaic of an object as it crosses the meridian. The logs show both the proper handling of the meridian flip and the poor behavior when switching from panel to panel in the mosaic. I've made some notes in the log and you can find them by searching for the string "????". In the meantime I'll be installing and trying to learn PHD2. Thanks for your help.

Thanks for reporting this. Your comments are on spot.
From the log, Scheduler does not stop guiding and capturing as it should when deciding to change the workflow.
It manages its decision as if it was a hiccup in a running observation, while it should properly stop guiding, stop capturing, slew around then restart procedures.
Because it is a workflow issue, the same problem(s) will probably happen with PHD2 as guider. PHD2 will eventually be more robust on recovering guiding.
We'll look into this as soon as possible.

What is surprising for me is, that we do not get a "lost star" event from the guider and at the same time a drift is reported from the guider.

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.
