Building upon the remarkable success of the acclaimed iOptron CEM60 centre balance equatorial mount, we are thrilled to unveil two new groundbreaking offerings – the CEM70. This innovative mount is poised to set new standards in the medium payload segment, delivering unparalleled performance and a host of advanced features designed to elevate your astrophotography and observational experiences.

At the core of these mounts lies iOptron's revolutionary centre balance design, a pioneering engineering approach that strategically positions the payload weight directly over the centre of the pier or tripod. This ingenious design principle not only ensures exceptional stability but also facilitates smooth and precise operation, minimizing frustrating vibrations and disturbances that can compromise image quality.

Equipped with an onboard optical guiding system, this cutting-edge mount sets a new benchmark for tracking accuracy, streamlining the imaging setup process and delivering unparalleled results.

Despite their relatively compact size, these medium payload mounts pack a powerful punch, capable of effortlessly supporting payloads up to 31.8 kg. Whether you're an avid astrophotographer seeking to capture the finest details of distant galaxies or a dedicated visual observer exploring the depths of the cosmos, the CEM70 offer the versatility and performance to bring your astronomical pursuits to new heights.

Precise GOTO pointing and accurate tracking (PE <±5 arcsec) are hallmarks of these mounts, ensuring that your observational and imaging experiences are free from frustrating inaccuracies and drift. The CEM70 is a solid performer catering to the needs of both observers and imagers alike.

But the innovations don't stop there. iOptron has thoughtfully incorporated a range of advanced operational features that set these mounts apart from the competition. The internal iPolar electronic polar scope, for instance, streamlines the polar alignment process, ensuring that your setup is accurate and efficient. Additionally, the easy lock drive gear engagement, with levers large enough to use while wearing gloves, adds a level of convenience that will be appreciated by all astronomers.

Furthermore, the advanced cable management system for the mount, iPolar, iGuider, and camera ensures a clutter-free and organized setup, minimizing the risk of tangled or damaged cables and contributing to the overall longevity and reliability of your equipment.
