About this product

Model:  iop_cem40ec_7400eca_1.5
Part Number:  7400ECA

Features include an integrated Right Ascension encoder! 

The iOptron® CEM40EC is a remarkably capable center-balanced equatorial mount and the first to feature iOptron's next generation design.

Weighing in at only 15.8lbs, it can support a payload of up to 40lbs. Which is remarkable! 

Features include iOptron's integrated electronic polar finder scope, known as the iPolar, which ensures accurate polar alignment even when the pole star is obscured. 

Large Clutch levers on the quick-lock drive engagement system make it easy to lock the gears into place. 

Innovative iOptron Technology

IOptron's patent-pending Universal Self-Centering Saddle 'USCS' accommodates Losmandy and Vixen-style dovetail plates. It also accepts Sky-Watcher & Celestron dovetails.

In addition the CEM40 features iOptron's ultra-quiet, low-power consumption stepper motor drive system for precise pointing and tracking. 

Computerised Mount Features

Using iOptron's Go2Nova® 8407 GOTO hand controller you can automatically point and centre any of the celestial targets (depending of course on date and location) contained in it's 359,000+ object database! 

With the included tripod, 4.5 kg counterweight and computerised GOTO technology, observers are just a telescope away from an impressive viewing experience!
