iOptron Mount CEM120EC GoTo High Precision Encoder (56286)

The iOptron CEM120 is an extraordinary innovation in equatorial mount design, created to meet the demand for a highly accurate and stable mount capable of carrying larger instruments and complex imaging setups. With a payload capacity of up to 52kg, it incorporates iOptron's revolutionary center balance design, which ensures natural stability by focusing the mount and payload's weight directly over the center of the pier or tripod. This design provides smooth mechanical operation and exceptional tracking accuracy.

The CEM120 features low periodic tracking error, advanced cable management to prevent tangling and damage, and modern conveniences such as Wi-Fi and LAN for remote operation. Reliable clutches on both axes make it easy to use, while precision adjustments for altitude and azimuth ensure accurate polar alignment. The mount is available in three versions: CEM120, CEM120EC (with high-resolution encoders for real-time tracking), and CEM120EC2 (with encoders on both axes for nearly error-free tracking).
