Product Description

Following up on the success of the iOptron CEM60 center balance equatorial mount, we at iOptron are excited to introduce two new medium payload center balance mounts. The CEM70 series mounts are new standard bearers for equatorial mounts in the 70lb payload segment.

The mounts 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.

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, the CEM70EC 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 designed with their needs in mind.

Teething Pains But Great Customer Support

Unfortunately I ran into an issue with the serial connection dropping out on my new mount. After a couple of nights of frustration, I reached out to iOptron's tech support. It took a few messages back and forth to narrow down the issue but they had me pull the board and re-seat the WiFi module. I was skeptical of that to fix the USB connection, but that was the trick.

I would have preferred not to have to go through that, but overall the mount itself is solidly built, responsive and quiet. A few things I might change, but nothing that is critical - especially for a mount that will reside on a concrete pier for life. :)
