Building on the triumph of the iOptron CEM60 center-balance equatorial mount, we're thrilled to roll out two groundbreaking medium payload center-balance mounts—introducing the CEM70AW, the new gold standard in the 70lb payload category. This mount is loaded with cutting-edge features like USB3.0 and Wi-Fi connectivity.

Staying true to the core principles of center balance, these moderately-sized yet powerful mounts deliver the efficiency, accuracy, and portability that astronomers and astrophotographers crave. With razor-sharp GOTO pointing and tracking accuracy of less than ±5 arcsec, the CEM70 delivers for both stargazers and snapshot takers.

We've added some cool new bells and whistles like the built-in iPolar electronic polar scope, gear engagement levers you can handle even with gloves on, and a streamlined cable management system that accommodates the mount, iPolar, guide camera, and your main camera. All this to say, we've designed the CEM70AW keeping you—the user—in mind.

What's more, the CEM70AW package comes with the iPolar electronic polar scope and a durable hard case to keep it all safe.
