I've created a simple Celestron CGX driver that can use the USB port on the mount, without the hand controller or special aux cable. It does not use the new alignment subsystem, so goto accuracy is limited, but goto, sync, park, and guiding work (in the northern hemisphere). PEC is not implemented yet.

Based loosely on the indi-celestronaux driver. Feel free to test.

I can guarantee this doesn't work in the southern hemisphere at the moment.

As a workaround, you can use CGX with the direct USB cable by treating it as a networked scope and running this command before connecting:

nc -l 9801 > /dev/ttyS0 < /dev/ttyS0

Just replace ttyS0 with your actual serial device name. Then you can connect to the scope as ethernet at 127.0.0.1 for the IP and 9801 as the port.

Yeah. I'm doing some testing now to see if I can figure out a way to automatically detect it. Might just need yet another switch on the driver to enable/disable the feature.

Thanks fabrizio. I'll take a look. For the CGX (and I imagine the CGX-L) we have a USB port of the mount itself that uses the same protocol as the RTS/CTS, just without the actual RTS/CTS. It would be awesome to be able to use that. Also, these mounts will go to HA=6, DEC=90 when then MC_LEVEL_START command is sent to both axes. This would make the first sync point very easy to add for these mounts.

Hey Fabrizio, where is the latest version hosted? Because the latest changes I see in master are from months ago.

Sounds good Jim. I'll reach out once I have something kinda working.

Yep. I created a service file to start on boot. And ctrl-c is the proper way to stop it.

Yes, it runs on a raspberry pi. The recommended way to run it is in docker.

No problem. If you have any issues, report them on github. I've been using it for a few sessions now, and it seems pretty stable running in docker.
