Hello there,

Sorry if I'm not on the right topic.

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.

Any leads to help me?
Thanks in advance.

Using the ST4 connection from a guide camera only provides guiding correction pulses. Surely, what you need is a cable from your mount (if necessary via the Hand Controller) to the RPi, or are you already driving the mount GoTo function?

Indeed, I had not imagined that the ST4 only made corrections.
I would like to use Kstar for the goto function. I think I will check the serial wire.

Thank you for your answer.

Regards
