I just purchased an STV autoguider. My mount is a Celestron CGEM. When I looked at the pinouts for the guide port it is different for these 2 devices. My question is: Do I need a special cable or adapter? If so, what is the part number and where can I order it? I have heard that some of the cables correct for the difference. Thanks
The STV was discontinued 10 years ago, so we don't have any adapters or accessories available. The STV manual may be helpful, see https://www.sbig.com/site/assets/files/18230/stv_manual.pdf
