The iOptron CEM40 is the latest and greatest in center-balanced EQ mounts. It's not just a pretty face; it performs like a champ, too. Despite weighing only 17.4 pounds, it can carry a whopping 40 pounds of equipment. How cool is that?
Upgraded Tech Features Say hello to groundbreaking tech. This mount comes with iPolar, an electronic polar scope that guarantees precise telescope alignment—even if Polaris is playing hard to get. Its quick-lock system has these hefty levers that let you engage the gears with a simple snap.
Compatibility & Motor System The CEM40's dual saddle is designed for both Losmandy and Vixen-style dovetail plates, offering you more options for your setup. Plus, it's powered by iOptron's whisper-quiet stepper motor, which keeps the mount tracking smoothly.
Smart Navigation Navigating the skies is a breeze with the Go2Nova hand controller. This bad boy taps into a database of over 212,000 celestial objects, helping you find your night sky targets effortlessly. If you're into sky-gazing and want an intuitive, feature-packed mount, this one's a no-brainer.
Everything But the Kitchen Sink The package comes complete with a tripod, an 11-pound counterweight, and all that fancy computerized tech. Just add an OTA (Optical Tube Assembly), and you're all set for some killer stargazing!
(P.S. This mount uses a #8027 counterweight, just so you know.)
