iOptron's CEM 40 with iPolar + iGuider
The iOptron® CEM40G mount is the next generation of center-balanced equatorial mounts with a built-in iGuider guiding camera. 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 17.5 lbs., the CEM40G can support a payload of up to 40lbs.! That's incredible!
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 iOptron Technology
Make way for an innovative mount! This iOptron CEM40G mount has a dual saddle that accommodates Losmandy and Vixen-style dovetail plates. The CEM40 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.
With the included tripod, 10lbs. counterweight, and the mount's computerized technology, observers are just an OTA away from a spectacular viewing experience!
