I am playing around with an inherited ETX125 circa 2007. I have it adapted for autoguiding, that is a separate light-weight autoguding camera can be adapted.
Will the ETX support autoguiding? I have a Shoestring GOUSB adapter and PHD installed. I am hesitant to plug something in the AUX port that sends ST4 standard signals out of concern I'll fry the scope board. Do I still need to dig up and buy the discontinued 909 cable-adapter to send Meade compliant signals to the ETX? Thanks - Canopus56
