iOptron CEM120EC2 Center Balanced Equatorial Mount With Extra High-Resolution RA-Axis/Dec-Axis Encoders

The iOptron CEM120EC2 Center Balanced Equatorial Mount was created by iOptron as a result of the growing demand for an accurate and stable equatorial mount with the versatility to carry larger instruments and more complex imaging arrays, with very high-performance specifications.

It offers the benefits of iOptron's revolutionary “center balanced” design: stability, accuracy, and smooth mechanical operation, while capable of carrying a payload up to 115 lb (52 kg). The “center balance” design’s natural stability is due to its focusing the mount along with any payload's weight directly over the center of the pier or tripod. The CEM120EC2 performance is demonstrated by its low periodic tracking error of  < 0.15 arcsecond RMS for this EC2 model. And it incorporates dual Hi-Res. Encoders (on both axes).

Along with stability, the CEM120EC2 Center Balanced Equatorial Mount features an advanced cable management system consisting of more ports in more locations, preventing cable tangles 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. This product is the CEM120EC2 High-Resolution mount, with dual Hi-Res. Encoders on the Right Ascension (RA) axis and also on the Dec axis.

This product's number is IOP-7302.
