So to autoguide you need to use a ST4 cable from the camera to the mount or are you saying autoguiding completely out of the question with the synscan driver?
Yes, you can use from camera's ST4 port to mount. What I meant in my previous post is that the mount itself does not support guiding directly from the PC using the INDI synscan driver. If you use EQMod driver, you can guide directly nonetheless.
