Hot on the heels of the wildly successful iOptron CEM60 center-balance equatorial mount, we're thrilled to roll out the next big thing—our CEM70 series mounts. These bad boys are game changers in the 70lb payload category. While both models come loaded with top-of-the-line features, the CEM70G is a pioneer, boasting an integrated optical guiding system. This not only amps up tracking accuracy, but also makes for a sleeker, more portable setup.

Staying true to the core advantages of the center balance design, these medium payload powerhouses don't disappoint. They give you exactly what you'd want—an accurate, portable, and efficient mount. Specifically, the CEM70EC offers pinpoint GOTO capabilities and nails it in tracking, making it a hit for both casual skygazers and hardcore astrophotographers.

Let's talk details. You're going to dig what we've built into the CEM70:

Features

A fresh center-balanced equatorial mount (CEM), built to carry a hefty load while staying rock-steady.
Perfect for peering through the eyepiece or snapping celestial shots.
70 lbs (31.8 kg) payload capacity, all packed into a 30 lbs (13.6 kg) mount.
User-friendly gear clutches you can count on.
Fine-tuned altitude and azimuth adjustments.
A stepper motor so precise, we're talking 0.07 arcsec accuracy here, for both GOTO and tracking.
Our internal iPolar electronic polar scope is thrown in for good measure.
The Go2Nova 8410 controller comes with Advanced GOTONOVA GOTO tech and a built-in heater—yep, it's that awesome.
Ultra-accurate tracking with a minuscule periodic error (PE < 0.3 arcsec rms), and real-time periodic error correction (RPEC).
Built-in 32-channel GPS because why not?
USB connectivity for all your devices.
An integrated ST-4 autoguiding port, making your life easier.
A flexible cable management system that plays nice with your mount, iPolar, guider, and camera.
A spring-loaded 8" Vixen/Losmandy dual saddle that'll win you over.
Plus, we're throwing in subsidized access to TheSky Imaging Edition software.

What's in the Box?

Box 1 of 2 (#C704A): You get the CEM70EC mount head, neatly packed in a hard case, along with all its cool accessories.
Box 2 of 2 (#7226): A 9.5 kg counterweight to round out the setup.

So, are you as excited about the CEM70 series as we are? They built it with you in mind, and we can't wait for you to take it for a spin.
