CEM70 Equatorial Mount for Telescope

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 that 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 CEM70 Equatorial mount for telescope offers outstanding load carrying capacity, WiFi connectivity, a built in USB hub as well as dual size dovetail that will fit both Losmandy and Vixen style dovetails. This mount can easily handle a telescope as large as an 11″ Schmidt Cassegrain complete with all accessories and cameras without any issues. If you want an Equatorial mount for telescope with room to grow and multiple connectivity options as well as good tracking performance, this could be the best option available.
