For connecting your autoguider, cameras or eyepieces it has a T2 thread and 1.25” socket. For exact adjustment to the main telescope, collimation rings are provided, each with 3 nylon-tipped screws. The guidescope bracket comes with a Sky-Watcher / Vixen style mini dovetail for standard finder shoes.
