iOptron CEM70 Center-Balanced Equatorial Mount with iPolar & iGuider

(Authorised Sales & Support by Modern Telescopes – India’s Largest Telescope Distributor)

Building on the legendary success of the CEM60, iOptron introduces the CEM70 series—a new benchmark in the 70 lb payload class. The iOptron CEM70 with iPolar™ and iGuider™ is a powerful, precision-engineered center-balanced equatorial mount designed for serious visual observers and advanced astrophotographers who demand accuracy, stability, and portability.

The innovative Center-Balanced Equatorial Mount (CEM) architecture places the payload directly over the tripod/pier’s center of gravity, delivering exceptional natural stability while keeping the mount compact and lightweight. With an impressive 70 lb (31.8 kg) payload capacity and a mount weight of just 13.6 kg, the CEM70 achieves an outstanding payload-to-weight ratio of 2.33, making it ideal for portable observatory-class imaging setups.

Precision Tracking & Astrophotography Performance

Engineered for high-end imaging, the CEM70 offers high-precision GOTO and tracking accuracy with periodic error < ±5 arcseconds, supported by PPEC (Permanent Periodic Error Correction) and precision stepper motors delivering 0.07 arcsecond resolution. Whether you are capturing deep-sky nebulae or running long-exposure astrophotography sessions, the CEM70 ensures smooth, repeatable tracking night after night.

Integrated iPolar™ & iGuider™ – Simplified Setup

The mount features an internal iPolar™ electronic polar scope, enabling fast, accurate polar alignment without contorting behind the mount. The onboard iGuider™ autoguiding system further streamlines your imaging train by eliminating extra guide scopes and cables—resulting in a cleaner, more reliable astrophotography setup.

Smart Design with Advanced Connectivity

The CEM70 is built with user convenience in mind. Large, glove-friendly clutch levers, precision altitude and azimuth adjustments, and an advanced cable management system keep power and data neatly routed through the mount. Built-in Wi-Fi, USB 3.0, ST-4 autoguiding, and 32-channel GPS ensure seamless operation with modern imaging software and observatory control systems.
