iOptron CEM120 center balanced GoTo mount with Dual High Precision Encoder

iOptron CEM120-EC2 GoTo Montierung for big telescopes up to 52 kg

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 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 CEM120´s performance is demonstrated by its low periodic tracking error of ±1.5 arc seconds. 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.

In opposite to the CEM120-EC, the CEM120-EC2 has high precision encoders in both axes which allowthe mount to save alignment models after power off too to be used on future nights. Thus the CEM120-EC2 is the ideal mount for remote operation. Additionally, 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.
