When purchasing digital setting circles for your telescope, you’ll also need to have encoders installed on your scope - without these, your Nexus DSC or Nexus II has no way of interfacing with your telescope. The encoders are attached to your telescope’s axes and send signals to your Nexus DSC/Nexus II, letting it determine the position of your telescope.
The GSO Dobsonian Encoder Installation Kit is created specifically for Dobsonian telescopes with spring tensioners on altitude bearings manufactured by GSO (Apertura, Bintel, Bresser, Omegon, Zhumell) and Orion (Classic Dobsonians - XT4.5, XT6/8/10).
