I just downloaded the latest Nightly, and it works much better. No crashes with alignment yet! The auto star and subframe still not working ☹️

I am using Lubuntu 18.04.
Is there any operational performance difference with Lubuntu vs Mate?

I too have Ubuntu 18.04. Both version 3.9 and 4.0 crash every time I use the assignment plate solving routine now. It crashes right before the FINAL iteration is completed, but AFTER the scope has moved. So I now have to wait for the crash, relaunch Kstars/Ekos, and continue. I've found that I can solve and sync with no problem, but solving and slewing crashes my system every time.

I spoke too soon. :(
It must have been a fluke, and that a star just happened to be in the right location.
All night long it continued to fail. The box would appear in the center of the field of view, regardless if there was a star in it or not - usually not. (90% of the time).

So the auto star function, and even the subframe selector failed. I would select a star, and as soon as I pressed the guide button, it would remove the green box and put it over an empty space.

This is with Lubuntu 18.04 and the latest download of the stable release of INDI and Kstars.

Does anyone have any ideas I can try?

I just upgraded my NanoPC T4 to Ubuntu 18.04 and so far all is working well!
It selected a star, put it in a box, and guiding is going great! :)

I just checked, and it is set as "Flip if HA > 2.25 degrees". There was an option to use "hours" but that was not checked.

Are you using the Ubuntu version of KStars/EKOS and using VNC or are you just connecting to INDI on the Ubuntu box from your Mac?

I have INDI running in Ubuntu 16.04 and connect via my MacBook. It fails every time. Perhaps it’s an issue with 16.04 Ubuntu?

Yikes! Maybe that’s it!

I will check and see if I have that set wrong!
But what about the auto star function? It still fails every time in both the guider and focuser.

Has anyone else had EKOS just start doing meridian flips for no reason? I was imaging along with no major issues when suddenly it decided to do a meridian flip- just over one hour from the meridian. The mount swung around but of course had to go back the other way again since it really couldn’t reach the target yet. This happened about every ten minutes of tracking and each time it then tried to find a guide star the whole imaging session ended because of the auto star select bug failed to find a guide star ( see my previous post on that). After three inappropriate flips I got so frustrated that I called it a night and gave up.


Each time the mount was tracking correctly, synced to the target, and KStars showed the correct location. The date and time was correct.

This has never happened before. EKOS is now so unreliable that I am ready to give it up entirely. It used to have a minor bug here and there, but now it is completely unusable for me. And I gave not changed any of my equipment or operating system in two years.

Is there anyone who has a reliable, working system?

Its been almost a year since the autostar function stopped working on my Ubuntu 16.04 box or Mac OSX. With every upgrade I hope it will work again, but so far not.
Without it, I can't use the scheduler or unattended meridian flip. It always selects an empty space, then fails to find a guide star or a focus star,.

Additionally the subframe does not work either, but I can live without that.

Peter Kennett created a new topic ' More accurate guiding deviation error option' in the forum. 4 weeks ago

Guiding errors are absolute errors, but the guiding deviation error monitor code does not see that.

For example…. let's say we set a guiding deviation error of 2 arc seconds, before canceling an exposure.
If we get an error of +1.5 then no exposure suspension is done. But let's say the error goes from +1.5 to -1.5 over the course of the exposure. That's an absolute error of 3 arc seconds, and would ruin the exposure.
This would explains why I see some trailed images, when no deviation error was detected.

I suggest EKOS measure the total ABSOLUTE amount of error over the course of the exposure. That would eliminate this problem.

I only have an issue like this on my Mac if I am saving files to the client (the NanoPC on the scope). Like rdricks stated, if I am copying files to local, or both, then I get the preview.

I will post an error log later today. But for thew last two nights, the align module keeps crashing when trying to Slew to Target. It seems to be fine, and does the first iteration of capture, plat-solving, and slewing with no problem. But on the second iteration it crashes to the desktop. I tried ASTAP and Astrometry and both fail the same way. Everything was fine before I upgraded to KSTARS 3.4, so this is a new bug. Using Ubuntu 16.4.
If Kstars no longer works with Ubuntu 16.4 let me know, and I will consider upgrading or just stick with KStars 3.9.
