Jasem, you rock! That last fix solved the guiding problem. I managed to get everything fired up and tested about a half-hour before a cold front rolled in and clouded everything out. The RST-135 slewed to Mirfak and plate-solved no problem. I then cleared the old calibration info out of Ekos and told Ekos to pick a star and start guiding. And that is exactly what it did!

Stopped guiding and slewed to M43, plate solved, and then clicked on guide again. Ekos worked flawlessly and was guiding and taking 30-second subs until the clouds rolled in and blocked the sky. Looking at the long-term weather forecast it'll be at least 2 weeks before I can test again. Maybe Andrew will get a shot at testing.

Thanks Jasem,
I'll update the software and hope for a clear night sometime during December. Not always an easy thing to find in the Seattle area during the winter months

Hi Andrew,
I have an RST-135 and I'm the exact same problem you're seeing even with the latest release of Stellarmate. Running the mount with Windows / ASCOM the mount works without a hitch. I've also heard it works fine with the ZWO ASIair Pro and I'll be testing that shortly. At this time I can't recommend Stellarmate and the Rainbow mounts as a working combination. Hopefully, it'll get fixed soon.
