Upgrade Your Vixen Equatorial Mount to Motorized GoTo Tracking
The R.A. Motor Module & STAR BOOK ONE Set adds motorized right-ascension tracking and GoTo control to compatible Vixen equatorial mounts — no new mount needed. The RA motor module drives your mount's right-ascension axis automatically, keeping celestial objects centered as the Earth rotates. The included STAR BOOK ONE hand controller adds multiple tracking modes, backlash compensation, Periodic Error Correction (PEC), and an autoguider port for serious astrophotography.
A micro-pulse stepper motor paired with a 140-tooth worm wheel delivers quiet, low-vibration motion — important for long-exposure imaging where vibration causes star trails.

- Vixen equatorial mount owners wanting to upgrade from manual to motorized RA tracking and GoTo
