The iOptron CEM70EC Center Balanced Mount Head proves that iOptron has done it again! Using ideas and engineering applied to a time tested design, the iOptron CEM70EC brings you the next generation German Center Balanced mount. An elegant CNC body is the first indicator the CEM70EC is a top quality mount; you will find this is true in both its form and its function. Utilizing clever engineering, they were able to provide the iOptron CEM70EC Center Balanced Mount Head an incredible 2.33 X payload-to-mount weight ratio. This iOptron CEM70EC Center Balanced Mount is also the advanced, high-performance "EC" Model, the C704A0. This heavy-duty mount can precisely GO-TO an object and track it with up to 70 lb of gear on-board, but while the Head weighs only 30 lb. An amazing feat. This model also includes the iOptron iPolar electronic Polar Scope.

The iOptron CEM70EC Center Balanced Mount delivers a Real-time Periodic Error of less than 0.3 arcsecond RMS. This is primarily accomplished by using a high-resolution optical encoder on the R.A. axis, and also by its advanced real-time RPEC error correction capability. This ensures the precision tracking you need for the best possible astro-imaging results, along with a great payload capacity and easy operation. The superb mechanical construction and choice of premium drive components for this mount provides the tracking and slewing performance you expect from iOptron. Retaining the inherent properties of the center balance design, this relatively compact medium payload mount delivers what astronomers expect in an efficient accurate portable mount. With precise GOTO pointing and accurate tracking (PE <0.3 arcsec RMS) the CEM70EC is a solid tracking and exceptional mount for both observers and imagers.

With its integrated electronic polar scope (iPolar Scope), polar alignment is a snap, even when the pole star is obscured. This model also includes the iOptron iGuider. Large levers are included on the quick-lock drive engagement system. These levers make it easy to engage its drive gears into place even when wearing gloves. There is little chance of your cables getting snagged with the CEM70's internal advanced cable management system. This iOptron CEM70EC Center Balanced Mount Head is the ideal, easy-to-use Center Balanced GoTo mount system for heavier telescopes or imaging systems, in the up-to 70 lb range, which will satisfy all your observing and astro-imaging needs for years to come. This mount is especially easy to set up and polar align with its included iPolar electronic polar scope.

A new, patent-pending Universal Self-Centering Saddle (USCS) accommodates both the Losmandy and Vixen style dovetail plates. CEM70 mounts utilize reliable stepper motor drive systems for accurate pointing and tracking. These motors have a low power-consumption technology. A 212,000+ object library with star identification for accurate GoTo performance, optical encoder system, and GPS are just a few of the desirable features standard on a CEM70EC mount.

NOTE: This product includes the mount head plus iPolar, plus one each 20.9 lb (9.5 kg) Counterweight, plus a Hard Storage Case. NOTE: NO tripod or pier is included with this Head.
