Riding the wave of success from our iOptron CEM60 center-balanced equatorial mount, we're stoked to roll out our latest game-changers in the 70lb payload category: the CEM70 and CEM70G. While both mounts are loaded with cutting-edge features, the CEM70G takes it a step further with an in-built optical guiding system, making it a trailblazer in its class. This feature not only enhances tracking precision but also makes the whole rig more travel-friendly.

Keeping the core advantages of the center-balance design, these medium payload champs offer everything an astronomer could want—accuracy, portability, and efficiency. With dead-on GOTO accuracy and tracking (PE <±5 arcsec), the CEM70 is a real heavy-hitter, ideal for sky-watchers and shutterbugs alike.

As for user-centric features, we've got you covered. The internal iPolar electronic polar scope, glove-friendly gear-locking levers, and a sleek cable management system are all part of the package. So, yeah, we've designed the CEM70 and 70G with you in mind. No compromises.

Features:
- Fresh, center-balanced equatorial mount (CEM) designed for top-notch payload capacity and intrinsic stability.
- Perfect for both stargazing and astrophotography.
- Carries up to 70 lbs (31.8 kg) while weighing in at just 30 lbs (13.6 kg).
- Gear clutches that are a breeze to engage.
- Fine-tune adjustments in both altitude and azimuth.
- Stepper motor precision at 0.07 arcsec—ideal for pinpoint GOTO and accurate tracking.
- iPolar™ electronic polar scope built in.
- Go2Nova® 8410 controller comes with Advanced GOTONOVA® GOTO tech and a built-in heater.
- Low periodic error (PE) tracking at <±5 arcsec.
- Permanent periodic error correction (PPEC).
- 32-channel GPS, so you always know where you are.
- USB connectivity.
- ST-4 autoguiding port integrated.
- Cable management system that gives you options.
- 8" Vixen/Losmandy dual saddle with spring loading.
- NEW iOptron subsidized TheSky Imaging Edition bundled in.
