The iOptron® CEM40 mount is the next generation of center-balanced equatorial mounts. This mount is incredibly eye-pleasing, and its beauty is found in more than its appearance. The functionality of the mount is superb. Weighing in at only 17.4lbs., this mount can support a payload of up to 40lbs! That's incredible!
Innovative iOptron Technology
Make way for an innovative mount! This mount 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.
This iOptron CEM40 mount has a dual saddle that accommodates Losmandy and Vixen-style dovetail plates. it 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 CEM40 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! For those looking for a telescope that has the capability of tracking and finding beautiful night sky objects, this mount is a must have tool.
iPolar included. Tripod and counterweight are not included.
