Starlight Instruments Electronic Focusers

Starlight Instruments electronic focusers motorize focusing so you can reach critical focus without touching the telescope, or let imaging software refocus automatically. The range includes the Focuser Boss II controller, the Handy Stepper Motor with manual override, the Posi Drive motor system and a motorized Gen II 3.0" Feather Touch.

Add-ons include wireless control, a hand controller, a two-focuser board upgrade and a focus motor for RedCat and SpaceCat refractors.
