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.

• 115 lbs payload capacity
• Tracking accuracy of less than 0.15 arcsec RMS
• 12 port cable management saddle
• LAN, RS232, USB and Wifi Control options for remote observatory setups
• Built-in 32 Channel GPS 

Note: If you are going to mount this atop an already purchased Tri-Pier (8034) you will need an adapter plate #IO-8036-120. (You can find this below in the Recommended Products card.) Otherwise we advise to get the IO-8037 Tri-pier which already had the adapter plate attached.
