It still appears to be an issue in 3.6.5 on Ubuntu. Wayland has been default in Ubuntu for three years. There should be a fix or workaround by now without switching back to X11.

Hi Jasem,

I've had a couple of issues lately, not sure of which may be eqmod issues and which could be Kstars, Ekos etc. The first one is, I've set the parking position to a low position in the direction of North, then powered down the system normally. Then the next day, starting up Ekos and connecting up the equipment, somehow the parking positon moved to the Southwest. I have tried setting it again to the North. Closing and reopening Kstars the parking positon set itself to the Southwest once again. Today I tried purging all settings and the parking position. This seemed to have worked, closing and reopening Kstars, the parking position stayed in place. What happened is, the scope imaged just fine until the meridian flip, but couldn't complete the flip, because it moved to the completely wrong direction. Afterwards I tried some things and the eqmod driver crashed, but Kstars also crashed. All of this came about after updating to 3.5.4 from 3.4.x version.

I attached some logs

Thanks! So then it's probably a system related issue? Like a system process stopping Kstars? Surely there wasn't anybody around to press close.

Sorry for the late reply Jasem,

I have been trying for the last week to get a backtrace. Unfortunately I haven't managed to, or I don't think so. I don't get anything when typing bt. You can see in the screenshot attached below. The log doesn't have any useful information either, no specific reason or sign of a crash. I am clueless as to what this might be, but I want to solve the issue, because my setup is so unreliable this way, that I'm practically afraid to run it and crack my sensor from thermal shock.

OK thanks!

Will do it and run it tonight to see what comes up. I've muted audio and enabled limited resources mode in FITS viewer in the mean time, and now I can't reproduce it with simulators anymore. I am, also planning to install Zram if this doesn't work, to see if it makes a difference as I suspect this may be an out of memory error.

Hi Jasem,

I came across an issue with EKOS the other day. It crashes a lot, very randomly. I narrowed it down to exposure downloads. The log is spammed with "[ org.kde.kstars.fits] - Reading FITS file buffer" until it finally crashes.
I was able to reproduce it in the latest nightly yesterday with the simulator. I need to resolve the issue, because I'm worried that the sensor in my camera will crack from thermal shock every time this happens.

I hope, I am screwing something up and you can help. Logs attached!

All the best and thanks in advance,
Florian

I also think it would be a great addition. It would be interesting to play with a camera that has essentially the same sensor as the ASI 290MC, but for essentially half the price. I think It may not be hard to add support in the future, as the camera is already supported on linux by the AstroDMx software package.

I have now successfully installed version 1.6 of the ASI driver. I can also confirm the offset entry is in the header. Thank you Jasem! This will save a lot of headache for a lot of us ASI users.

All the best,
Florian

Hi Dirk,

That's awesome! I have not managed to recompile Indi3rdParty yet. It fails on dependencies of the Atik Driver. Havent'had time to investigate yet, but I'll try again today.

All the best,

Yup, I now see, Thanks! I am not on ASI Driver 1.6 yet. I can't imagine why, since I built everything from source again. Will try Again.

Thanks Jasem!

I have built from source from Git. I don't seem to get the entry in the FITS header, but I don't know a way to verify If I actually have the right version. KStars itself reports version 3.4.0. in the logs(quoted below). Do you think I have the right version?
