    Innovative iOptron Technology

    The GEM45 mount uses iOptron's patent-pending Universal Self-Centering Saddle (USCS). This saddle accommodates both Losmandy and Vixen-style dovetail plates. This mount also uses iOptron's ultra-quiet, low-power consumption stepper-motor drive-system, aiding the mount in providing precise tracking.

    The iOptron GEM45 mount uses the Go2Nova 8407 hand controller to navigate the night sky. This technology helps observers find celestial objects with the aid of the mount's 212,000+ object database. For those looking for a telescope that has the capability of tracking and finding night sky objects, this mount is a must-have tool.

    With the included tripod, 10-pound counterweight, and the mount's computerized technology, observers are just an OTA away from a spectacular viewing experience!
