Hey Ronald,

Thank you for your detailed reply.

I used the direct version of the driver a lot with my AZGTI and in the end it worked somewhat and I was able to minimize the tracking drift (see here ). The guiding also went well in principle (both axes - also with PHD2), but I had the impression that I couldn't beat the rest of the drift (it rocked up).

That's why I'm now testing the Synscan indi driver with the synscan app. There the drift is still better (with three star alignment model) and I think it might be possible to use the guiding successfully, but as described the guiding pulses from the calibration don't seem to be transferred to the mount at all.

Regards,
Mat
