That's just the driver for the CEM120, right? I don't know off-hand which one that is using, but my iOptron CEM25 and SmartEQ mounts do not show that behavior and they use the ieq driver and CEM60 driver, respectively.
Jasem, thank you for the update. The rotation is correct now. But the program tries to take a photo BEFORE the dome has rotated into position, so the images are blank and the alignment routine fails!
