Product information

An extraordinary innovation in mount design...Now with a new payload!

Recognizing the growing demand for an accurate and stable, equatorial mount with the versatility to carry larger instruments and more complex imaging arrays, we created the iOptron CEM120EC. It offers the benefits of our revolutionary “center balance” design: stability, accuracy, and smooth mechanical operation, while capable of carrying a payload up to 115 lbs (52 kg). The “center balance” design’s natural stability is due to its focusing the mount along with payloads weight directly over the center of the pier or tripod.

The CEM120EC's performance is demonstrated by its low periodic tracking error of <0.15 arcsec RMS. Along with the stability aspect, the CEM120EC features an advanced cable management system consisting of more ports in more locations preventing tangle ups and reducing the chance of fractured cables. It also adds some new features to the CEM family like Wi-Fi and LAN for remote operation and easy to use, reliable clutches on both axes.

Optional heavy duty Tri-Pier 360 and Permanent Pier are available for order.

Optional Tri-Pier adapter for light weight payload ( 8036-120) is also available. It can be modified for permanent pier mounting.
