I noticed something strange with the scheduler recently.

I have a script that auto-generates a schedule file based on some external data source (AAVSO observing targets).
This schedule file can contain many jobs. When I load this into EKOS 9 (say at 8pm at night) It always sets the start time of all jobs to tomorrow night. Making it impossible to use the scheduler right now.
However..... If I delete some jobs, save this file and re load it, the scheduler will schedule the jobs for tonight.

I'm not sure what could cause this. Either a bad job or its the number of jobs in the schedule.

I've attached a zip file with the large schedule (15 jobs) that I can't use and the smaller one that works.

Wondering if any scheduler experts could have a look?



Something abnormal happened this evening. I set the scheduler running and it waited until dark to start (all good so far)
I came back later to check how it was doing and the mount was parked but the roof fully open.
Looking into the logs it looks like a coms problem to my mount, the scheduler fails and then shuts-down. However, the shutdown procedure failed and then the roof was left open.

I'm just wondering if there is any way that it should at least try to close the roof/dome if there is a problem shutting down.

Pasted some of the log below.

Yes sorry for not clarifying. I replied on the other thread. I have a unihedron SQM connected with INDI. That would be a requirement to measure it. Maybe it does not fit here in the analyse tab as its an external thing

Thanks for the explanation Wouter,
I had a feeling alright that if it was mid capture it would not flip. This is ok, I'll just try to set what you have set above and I think it will reduce the risk of it not flipping.

Thanks Hy,

I was thinking of SQM from a unihedron sky quality meter. If there is one is connected to INDI then collect data from it. I think its probably very difficult to estimate real SQM (in units of MPSAS) from an image.
So basically if there is an SQM device and it is connected with INDI, collect that data every x min or at every capture.

Yes, I have that after focus correction :-) As a work around I include a 10second wait in all my Ekos sequences. That 10 seconds is usually enough for the guiding to get back on track. I was thinking to try and not suspend guiding during focus next time and see how it goes.

Thanks again for this amazing feature!


Is there any option in Ekos to tell it to stop saving the WCS headers when it saves a capture?

I find I have some problems with my automated scripts which are based on astropy. 2 Problems I have are
1) RADECSYS keyword is deprecated
2) The solve is not as 'good' as what I need.

I have a script to delete the WCS headers and then run astrometry on the fits files again. But I'd like to avoid doing that and just not save any WCS headers from Ekos if possible,

Could anyone with a CEM120 share their settings?

I seem to have lost my settings or something. This was working for me.. Last night my mount got 'stuck' at the meridian. I think it happened mid-capture.

I had EKOS set to flip at 0.15deg past the meridian. I don't know what the mount settings are at the moment.
It's not a major issue but it stops the scheduler from doing any more work.
If someone could share what they set in the mount's handset and in EKOS it would really help.

Maybe it's not that new. I generally don't update too often once I have a stable setup B)

I updated recently and got this new addition to Ekos. Thanks to the team that added it!!! It's fantastic. When I saw it first I wasn't sure I'd use it but Its very very good.

A nice addition in future would be to have SQM too. It's great to see how HFR changes over the course of a night but would be cool to see SQM too.
