The CEM70 and revolutionary CEM70G are iOptron‘s standard bearers for equatorial mounts in the 70lb payload segment.

Retaining the inherent properties of the center balance design, the CEM70 and CEM70G are relatively compact medium payload mounts deliver what astronomers expect in an efficient accurate portable mount. With precise GOTO pointing and accurate tracking (PE <±3.5 arcsec) the CEM70 is a solid performer for observers and imagers alike.

Innovative operational features such as the internal iPolar electronic polar scope, easy lock drive gear engagement (levers large enough to use with gloves), an advanced cable management system for the mount, iPolar, guider, and camera, and cumulatively assure users the CEM70 and CEM70G designed with their needs in mind.

The CEM70G includes the iPolar electronic polar scope, iGuider, onboard autoguiding camera and a hard case.
