The iOptron CEM120EC2 has ultra high resolution optical encoders on BOTH RA and DEC axes for the ultimate in tracking accuracy.
Recognising the growing demand for an accurate and stable, equatorial mount with the versatility to carry larger instruments and more complex imaging arrays, iOptron created the CEM120. It offers the benefits of the centre balance design: Stability, accuracy, and smooth mechanical operation, while capable of carrying a payload up to 115 lbs (52 kg). The centre balance designs natural stability is due to its focusing the mount along with payloads weight directly over the centre of the pier or tripod.
The CEM120's performance is demonstrated by its low periodic tracking error of ±3.5 arc seconds RMS. 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.
