Description

Introducing the new iOptron CEM120 center balance equatorial mount.

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 CEM120.  It offers the benefits of our revolutionary “center balance” design: stability, accuracy, and smooth mechanical operation, while capable of carrying a payload up to 115lbs (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 CEM120s performance is demonstrated by its low periodic tracking error of +/- 3.5 arc seconds and down to <0.15 arc sec RMS with the EC model.  Along with the stability aspect, the CEM120 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.  The CEM 120 will initially be available in two versions, the CEM120 and the CEM120EC (The EC version has high resolution encoders for real time nearly error free tracking, the EC2 version has encoders on both axes).  

The CEM120 and CEM120EC are available to order now and will start delivery end of December 2017.
