Made for long observation sessions, Vixen's Sphinx SX2 Motorized Go-To Equatorial Mount features precision motors and gears for accurate long-duration tracking. Dual stepper motors provide smooth and virtually vibration-free tracking that run at up to 250 pps. Its full-circle brass wheel gear allows the mount to track over extremely long periods with little error. The RA and DEC motors are situated inside the mount to reduce interference, and act as counterbalance for smaller scopes, eliminating the need for the counterweights and shaft. When not in use, the counterweight shaft retracts into the mount and out of the way. The mount and hand controller are powered by an included 12 VDC power adapter that simply plugs into any car/vehicle accessory socket.

The Sphinx comes with the Star Book One hand controller to help find, observe, and track celestial objects. While not a true Go-To system, it will require you to manually align the mount and find the subject, it does offer many performance features associated with those systems such as variable slew speeds, different tracking rates, and PEC and backlash compensation. Since near and deep sky objects appear to move at different speeds the controller features celestial, solar, lunar, and King's rate tracking speeds; in addition to slew speeds from 0.01x to 1000x. An integrated autoguider port adds to the mount's overall usability.
