Hot on the heels of our game-changing iOptron CEM60 mount, we're stoked to roll out the CEM70 and its next-level sibling, the CEM70G. These bad boys are set to redefine what you can expect from a 70lb payload equatorial mount. While both are decked out with high-end features, the CEM70G takes it up a notch with its groundbreaking onboard optical guiding system—boosting tracking accuracy and making your setup more portable than ever.
Still loyal to the core concept of center balance, these mounts are your go-to choice for stellar performance in a convenient, portable package. Expect laser-sharp GOTO pointing and on-point tracking with a periodic error (PE) of less than ±5 arcsec. Whether you're into star-gazing or capturing the cosmos through a lens, these mounts got you covered.
And let's talk user-friendly features. From an integrated iPolar electronic polar scope to gear clutches that you can easily lock—even with gloves on. The advanced cable management system sorts out not just the mount but also your iPolar, guider, and camera cables. Oh, and did we mention? The CEM70G comes WiFi and USB 3.0-ready right out of the box.
So what's in the CEM70G package, you ask? You'll find an iPolar electronic polar scope, iGuider onboard autoguiding camera, and a durable hard case.
Feature Highlights:
- Redesigned center-balanced equatorial mount (CEM) for an unmatched payload-stability ratio.
- Perfect for both visual astronomy buffs and astrophotography pros.
- A payload capacity of 70 lbs (31.8 kg) while weighing in at just 30 lbs (13.6 kg) itself.
- Gear clutches that are a breeze to use.
- Altitude and azimuth adjustments you can count on.
- Stepper motor delivering a killer 0.07 arcsec accuracy for GOTO and tracking.
- iPolar electronic polar scope with built-in heater.
- Go2Nova 8410 controller integrated with advanced GOTONOVA GOTO tech.
- Low periodic error (PE) of less than ±5 arcsec with permanent correction.
- Onboard iGuider autoguiding system.
- 32-channel GPS for pinpoint accuracy.
- WiFi and USB 3.0 connectivity.
- Multiple options for cable management.
- Comes with an 8" Vixen/Losmandy dual saddle that's spring-loaded.
- Bonus: iOptron-subsidized TheSky Imaging Edition software.
