When purchasing digital setting circles for your telescope, you’ll also need to have encoders installed on your scope - without these, your Nexus DSC / Nexus II has no way of interfacing with your telescope. The encoders are attached to your telescope’s axes and send signals to your DSC, letting it determine the position of your telescope.
The Explore Scientific Twilight I Encoder Installation Kit is created specifically for Explore Scientific Twilight I mounts.
