We're at the limits of my knowledge. I don't know if Ekos and the mount communicate regarding geographic position. I can imagine a scenario where they could properly sync on a target without agreeing on the geographic position of the mount, and thus when the meridian flip is necessary.
Looking at the manual, I see that the EQ6-R does not have a GPS. "At the end of the initialization of the SynScan hand control, after entering the proper local longitude, latitude". If you did not do this at least once after receiving the mount back perhaps it doesn't have the right coordinates?
Is that consistent with the hour angles reported in the log?

(Were the mount and Ekos in agreement on the geographic location of the mount?)
My guess is that you hadn't yet tracked far enough past the meridian for the mount to switch to the east side when it received a goto command from Ekos.
I removed the astrometry driver from my equipment profile. Curiously, it was still showing up when I started Ekos. I had to reboot the Stellarmate to have this change take effect.
After the remote astrometry drive was removed, Ekos no longer offers the astrometry tab unless the camera is present. When the camera is present, the four-click sequence does not crash.
Nonetheless, it would be good if KStars did not crash in the situation of my original configuration.
Thank you for your reply.
The astrometry driver is a legacy of my original setup. I didi not think to remove it but will do so.
The camera is not showing up because it is unplugged when my scope is in the garage. Of course a camera is necessary to solve, but KStars shouldn't crash if one isn't available.
I do not have log files to offer, but if you are unable to reproduce the crash just let me know what you need and I'll get them for you.
I have a ZWO ASI6200MC camera. For a recent image, the FITS file contained an astrometric solution and also notes that the data are to be interpreted top-down. FITS header excerpt:
ROWORDER= 'TOP-DOWN' / Row Order RA = 2.336768E+01 / Object J2000 RA in Degrees DEC = 3.063624E+01 / Object J2000 DEC in Degrees CROTA1 = 2.4249720376E+02 / CROTA1 CROTA2 = 2.4249720376E+02 / CROTA2

That sounds great, thank you. It sounds like that will be perfect. I will anxiously await the updated new version.
Are the streaming properties available via the Stellarmate Android app?
I set up my mount for every session, and its polar alignment routine requires me to see live view through the OTA while standing at the scope. Currently I use a Canon DSLR and can view the image on the back of the camera. But I am considering purchasing a dedicated astro camera that does not offer this. It is a very expensive purchase, so I am trying to make sure I will be able to see the live image for polar alignment.
I did some testing with my current DSLR and the app, and can get a sufficient frame rate. However, I do not know whether this will be true for the new camera without adjusting the streaming properties.
If I cannot use the app, I guess my solution may be to carry my laptop out there for the alignment.
In either case, it would be extremely helpful to be able to superimpose a crosshair at image center over the live view. Is that possible?
