Did you figure out what COM port the converter offers you? I found that
com port numbers >9 do not work.
If the system gives you com ports >=10, you should delete the unused
comports, so that you get a proper com number in the end.

Secondly, the NexStar option in Guide does not work with the more
recent Celestron mounts. Use ASCOM and the Celestron Unified Ascom
Driver (5.0.23).
