There appear to be 2 drivers that may be associated with the CGEM mount. One is listed as 'Celestron CGEM', and the other is listed as 'Celestron NexStar'. Which one should I be using? The same problem is seen with both drivers.
After performing a series of diagnostic steps requested by Celestron Technical Support, they had concluded from my description of the problem and the results of the diagnostic steps, that the problem must be with the Stellarmate software. Chris, you have been extremely helpful with investigating the issue. And the logs support my conclusion that although the problem is experienced when the mount is connected with the Stellarmate, the failure is in the communication between the Celestron mount and the Celestron hand controller. I am not yet willing to give up on Stellarmate because it is the best tool for my requirements. And I am not ready to dump the CGEM and purchase a different mount. As a retired engineer with hardware design and software development and testing experience, I know that this is a solvable problem and one I can solve if I have the appropriate tools. Celestron has agreed to provide me with a NexStar hand controller with a serial port to test. In addition to that, I plan to probe the Celestron internal communication bus with an oscilloscope to see if there any apparent electrical changes when the Stellarmate is connected. Beyond that, I would need guidance and diagnostic tools from Celestron to investigate the issue. It remains to be seen how much support they would be willing to provide.
Chris, Thank you for your help. Let me know if you have any connections with Celestron that might have the knowledge to assist with this investigation.
