Product Overview

Introducing the new iOptron CEM120EC 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 <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 CEM120EC2 utilizes two high resolution encoders, one on each axis. The two encoders enable the mount to perform dual axes tracking. With advanced sky modeling the CEM120EC2 will be able to account and adjust for polar alignment error as well as changes in atmospheric (refractive) distortion. Fixed home sensors on each axis, allow the mount to save alignment models after power off too to be used on future nights.

* These are only guidelines. Some telescopes are very long or very big for their weight and may require a larger mount. Remember also that imaging requirements are more rigid than visual observation.
