  With the growing demand for accuracy, heavy capacity, stability, and versatility in an equatorial mount, iOptron created the CEM120 to meet all these needs. The CEM 120 like all center balance designs are naturally stable is due to putting the weight of the telescopes directly over the center of the pier or tripod.

  The mount’s performance is demonstrated by its low periodic tracking error that is +/- 3.5 arc seconds RMS. The CEM120 features an advanced cable management system consisting that prevents tangle ups and reduces the chance of fractured cables. It also adds some new features to the CEM family like Wi-Fi and LAN for remote operation.
