iOptron CEM70G with iGuider – Center Balanced Equatorial Mount on Sale

iOptron CEM70G with iGuider – Center Balanced Equatorial Mount

The CEM70G with iPolar and iGuider

Following up on the success of the iOptron CEM60 center balanced equatorial mount, iOptron is excited to introduce two improved medium-payload, center balanced mounts. The CEM70 and revolutionary CEM70G are standard-bearers for equatorial mounts in the 70-pound payload segment. Both models are packed with advanced features however the CEM70G is the first of its type with an onboard optical guiding system increasing tracking accuracy while streamlining the components resulting in a more portable imaging setup. 

The center balanced design

Retaining the inherent properties of the center balance design, these 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.

iPolar electronic polar scope and iGuider included

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, iGuider (guider, and camera), and cumulatively assure users the CEM70 (for this choice see item #IO-CEM70) and this model CEM70G designed with their needs in mind. On top of the built-in guiding system the CEM70G also comes standard with WiFi and USB 3.0. 

The CEM70 and the CEM70G are economically priced, including the iPolar electronic polar scope and a hard case.
