Made for long observation sessions, Vixen's Sphinx SX2 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 Sphinx comes with the Star Book One (SB1) hand controller to help find, observe, and track celestial objects. Since near and deep sky objects appear to move at different speeds, the SB1 features celestial, solar, lunar, and King's rate tracking speeds. An integrated autoguider port adds to the mount's usability.
