I have a CEM40 and am trying to use BackyardEOS (BYE) to plate-solve and align the mount. I have the plate-solving with ASTAP working now, but when the process completes BYE is supposed to sync the mount to correct the pointing error. That's not happening. I posted this on the BYE forum and was told, "you need to make sure you set your telescope ASCOM driver to 'SYNC ALIGN' and not 'SYNC APPEND'. This is the most common mistake." But I cannot find any place to make this change in the iOptron driver.
Does anyone have any experience with this who can point me in the right direction?
