Thanks for testing, Willem.

Regarding "automatic mount model": Am I assuming correctly you're using the "Mount Model Tool" which can be started in EKOS Align Tab by the button "Mount Model"? I tried this with CCD simulator as well and I did not observe any issues. But I will test it again tomorrow. Did EKOS crash or the hand controller?

Regarding Firmware Version: There's obviously a small bug in the data field. It seems to append the serial number of the mount which is not intended. This did not happen during my tests but to be honest, I somehow deleted my mount's serial number while reverse engineering the "hidden" serial commands... devil.png I will try to fix this issue – but most likely will be difficult since I'm not able to test it live. BTW I found some more commands but was not able to map the mount's answers to corresponding functions correctly. This is very likely not intended by Rainbow Astro as well.

Regarding pulling of V&T: I made this optional and turned off by default because I was not sure whether everyone is interested in this information and if active in sum three serial commands are being continuously sent (limited by set pull rate) additional to the mount's more important data like RA/DEC & ALT/AZ positions. Unfortunately I did not figure out how to store the setting in the driver's config file yet – this would be the most convenient solution.
