I have a (old) Celestron C6 on AS GT Nexstar mount. I have a ZWO USBTOST4 cable and now, a Rasbery with Astroberry OS.
In the Ekos menu, I don't see the USBTOST4 driver. Did I miss the documentation page? Is there a driver for this type of configuration?
I saw that I could also use a very old serial cable to connect the racket to the PC but I would like to use this ST4 cable.
