Just installed and tried. Got a crash.

Reason: no suitable image found. Did find:

Hmm Libwcs was what was giving me trouble earlier this week. I thought I fixed it. I will check it to make sure

Yes, you were quite right. The file that was in the frameworks folder for libwcs6.3 was not correct. Apparently after I fixed the libwcs build problem yesterday, I forgot to tell it to rebuild the astrometry.net binaries that were getting included in KStars. Thus, it was still pointing to the broken file instead of the newly fixed one I made yesterday afternoon. Thanks for finding that. I will build a new dmg now.

Ok I just replaced the dmg with a new one with a fixed astrometry build that now points to the correct libwcs. Please check to see that it's fixed. And look for anything else.

I managed to get out for one night with the last version. It was crashing repeatedly during guide calibration. It would take about 5-10 frames then lock up. I reverted back to the last official release and things went back to normal. It’s possible this is driver related. Have a ZWO 120mini guide cam.

Well if it is crashing for you, we should see why that is. Please test the version I posted and see if there is anything predictable about it. Logs could really help. If we are going to release a new version, it would be good to make sure everything is working pretty well.

No crashing for me on macOS Mojave.
Rob, you've done a beautiful work on the Observatory Panel. Thank you.
I found a small bug : if I enter in the field "Absolute position the dome should move" the angle of the home sensor (say 73°), the dome turns 73° + 360° instead of turning only 73°.
It works as expected if I enter another value .
The astrometry seems to work OK. I will test it more carefully to-night.

Another bug appears if I click on the shutter "Opening" button : the dome turns more than 360°, with no way to abort the motion.
My system has a manual shutter, not a motorised one. A checkbox should be included to take into account this possibility. In fact a motorised shutter is useful for remote observatories or for a fully automatic operation of a local observatory.

Hi Jean-Claude,
maybe we should start a separate thread on the observatory. I started to develop this module originally with the intention to keep its functionality separated from the scheduler. Since I do not own an observatory, I have to test everything with simulators.

Which observatory driver do you use? Maybe I can find a hint directly in the source code - or we test it together...

Hi Wolgang,
I'm using the driver indi_maxdomeii version 1.3
I would be happy to help you for the tests and we could do it whenever it suits you
Here is my address jcjesior at free.fr

Here's the logs from my two crashed sessions. In both sessions, the guiding calibration failed due to stalled frames from the guide camera. Not sure what was going on. Reverting back to 3.3.1 fixed the issue. For both these sessions on 3.3.3 I restarted between them to clear any issues.

Hi Jean-Claude,

I can't take credit for the Observatory module, that is all Wolfgang. You can certainly help him improve it if there are any issues. Just let me know when and I can built another DMG for you to test any changes. If you want to get more immediate feedback to how any changes he makes will affect things, or if you want to try to make any changes for yourself, you can run my build script to build kstars for yourself. I can show you how.

Thanks,

Rob
