iOptron CEM120 EC2 Center Balanced EQ Mount with Dual High End Encoders

With the growing demand for accuracy, heavy capacity, stability, and versatility in an equatorial mount, iOptron created the CEM120 to meet all these needs. The CEM 120 like all center balance designs are naturally stable is due to putting the weight of the telescopes directly over the center of the pier or tripod.

The mount’s performance is demonstrated by its low periodic tracking error that is less than 0.15 arcseconds RMS. The CEM120 features an advanced cable management system consisting that prevents tangle ups and reduces the chance of fractured cables. It also adds some new features to the CEM family like Wi-Fi and LAN for remote operation.

The CEM120EC2 has fixed home sensors on each axis. Because of this alignment models are saved and can be reused on future nights as long as the mount is not physically altered after power off. It also can be “homed” through software if position is lost.

mediocre performance and poor support from the vendor

It turns out that most of these mounts do not meet their specifications. Mine certainly doesn't. Despite lots of attempts to engage the vendor to remedy the problem or ot give me a replacement that does meet the specification, they refused. My most recent polite question about the situation was met with no response at all. I'd stay away from any iOptron mount with encoders if you have a long focal length telescope.
