iOptron CEM40ECA Mount with 1.75-inch LiteRoc Tripod

The iOptron CEM40EC mount with integrated + iPolar and 1.75-Inch LiteRoc Tripod is the next generation of Center-balanced Equatorial Mounts.

Weighing in at only 15.8-pounds, this mount can support a payload of up to 40-pounds.

This mount also has an Integrated Electronic Polar Finder Scope known as the iPolar. This tool ensures the accurate alignment of a telescope, even when the pole star is obscured. There are Large Levers on the quick-lock drive engagement system; these large levers make it easy to snap the gears into place.

Innovative Technology: Make way for an innovative mount! This iOptron CEM40EC mount uses iOptron's patent-pending Universal Self-Centering Saddle (USCS). This saddle accommodates Losmandy and Vixen-style dovetail plates. The CEM40EC also uses iOptron's ultra-quiet, low-power consumption stepper motor drive system, aiding the mount in providing precise tracking.

Computerized Mount Features:  The iOptron CEM40EC mount uses the Go2Nova 8407 hand controller to navigate the night sky. This incredible technology helps observers find celestial objects with the aid of the mount's 212,000+ object database!

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