I recently purchased an EXOS-2 PMC-Eight mount to use for EAA. After performing a physical polar alignment using SharpCap and powering the mount on from the parked position, I find the mount cannot slew anywhere near the target when using the built-in GoTo functionality (ExploreStars app) or when using the ASCOM drivers. In most instances, the mount position is off by at least 10 degrees.
I have essentially the same results after performing a virtual two- or three-star alignment, as well.
I have now taken the mount out on three different nights without successfully getting the GoTo functionality working. Last night (the third night), I tried doing a three-star alignment after lining up the NCP using the mount’s polar scope. I intentionally used Merak as the first and the third star (and Schedar as the second star) to see what would happen. When the mount slewed to Merak to perform the third star alignment, its position was nowhere close to Merak despite having already synced on Merak as the first star.
I have used EQ mounts before, but this is the first EQ mount I have owned. Am I within the realm of possible new
user owner error, or do folks think it is likely I have a defective unit?
