Introducing iOptron's new compact next-generation center-balance equatorial mounts the CEM26 and CEM26EC. Like their predecessors the CEM26 is designed with portability in mind, weighing in at only 10 lbs it can support up to a 261b payload an incredible 2.6 mount weight to payload ratio. The key to enable such ratios is the CEM design focuses the mount and payload weight directly on the center of the tripod rendering "natural stability".

Building on the legacy of earlier CEM models we have added features for convenience and functionality. A positive lock gear engagement system (easy to use even when wearing gloves), Built-in Wi-Fi enabling unparallel connectivity and recordable permanent periodic error correction (PPEC) to repeat optimal PEC training sessions (real time PEC on the CEM26EC). Regarding functionality the CEM26 and CEM26EC delivers precise pointing and accurate tracking (PE <0.3 arcsec RMS on the EC model). The 212,000 object library ensures you'll never run out of targets to see or image. The CEM26 and CEM26EC set the new standard for compact equatorial mounts.

John ★★★★★

I was pleasantly surprised by how easy it is to carry around since it's only about 10 pounds, and the center-balance really helps with stability even on a tripod. Machined parts feel solid, no wobble at high speed slewing.

Samuel U. ★★★★★

The center-balance design makes setup so much quicker than my old German equatorial mount, and at just 10 pounds it’s easy to carry to dark sites. Tracks smoothly even with my heavier telescope—no complaints so far.

Olivia H. ★★★★★

I've been using this mount for a few weeks now and the center-balance design really does make setup quicker since I don't have to fight with awkward counterweight positioning. The 10-pound weight is a huge plus for me—it's light enough to grab and go for dark sky trips without sacrificing stability.
