iOptron CEM120EC Equatorial Mount

iOptron's CEM120EC was created after recognizing that there was a need for a precise yet durable equatorial mount, capable of carrying heavier payloads and more intricate imaging arrays. The mount maintains all of the popular benefits of iOptron's cutting-edge "center balance" design, such as accuracy, natural stability, and smooth mechanical operation. This heavy-duty mount is also able to accept up to 115 lb. payloads. By focusing the weight of the mount and payload directly over the center of the pier or tripod, the CEM120EC Equatorial Mount offers natural stability.

A low periodic tracking error of <0.15 arcsec RMS demonstrates the CEM120EC's performance. In addition to its natural stability, the CEM120EC contains an advanced cable management system that prevents entanglements and broken cables by providing additional ports. The CEM120EC provides the CEM family with some new features like WiFi and LAN for remote operation and clutches on both axes that are easy to use and reliable.

Alexander ★★★★★

After years of fighting with lighter mounts that wobbled under my 14-inch scope, this thing is rock solid and the center-balanced engineering makes it feel like the load isn't even there. Setup took a bit of patience, but once I dialed in the backlash settings, tracking is so smooth that my 10-minut

George G. ★★★★★

The payload capacity is no joke—I’m running a 40-pound scope and the tracking is rock solid even in gusty conditions. The internal cabling is a lifesaver for keeping everything tidy during a long imaging session.

Evelyn ★★★★★

Set-up took a full evening, but the strain on my back was worth it — the CEM120EC's center-balanced design makes swinging a heavy telescope around feel almost effortless. Guiding has been rock-solid all night at high magnification, and the payload capacity means I'm finally not worrying about gear w
