I am trying to use the 120m and 174m as guide cameras....which ASCOM drivers should I be selecting when using the Celestron CGEM mount?
you can use the "ASI Camera ASCOM driver"
PHD2 support ASI cameras nativly
so you don't need ASCOM driver
What driver should be used for the MOUNT if I am using a Celestron CGEM mount? I am using PHD2 and Maxum DL.
"On Camera" if you use ST4. Celestron ASCOM mount driver if via RS232-USB-computer.
