iOptron Mount CEM40-EC GoTo High Precision Encoder with Tripod

The mount head of the CEM40 weighs a mere 8.2 kg yet boasts a remarkable payload capacity of up to 18 kg, resulting in an exceptional payload-to-weight ratio of 2.5, rendering it incredibly versatile. Whether you're trekking to your favorite spot beneath a starry night sky or setting up in your backyard observatory with a modest pier, the CEM40 delivers.

But the benefits don't end there:

• An integrated electronic polar finder scope (iPolar) ensures precise alignment, even when the pole star is obscured.
• Large levers on the quick-lock drive engagement system allow for easy gear adjustment, even while wearing gloves.
• The internal cable management system minimizes the risk of cable snags.
• Equipped with the new Universal Self-Centering Saddle, accommodating both Losmandy and Vixen style dovetails.
• The CNC body not only looks sleek but also offers robust durability.

The GoTo-Technology is powered by a Go2Nova 8407+ controller featuring an integrated heater for its large display, a vast library of 212,000 objects, integrated 32-channel GPS, and an ST-4 auto guiding port.

Another standout feature, in addition to its center balance, is the ultra-quiet, low-power consumption stepper motor drive systems. Both models of the CEM40 are precision trackers, with the CEM40-EC version boasting <0.25 arcsecond accuracy thanks to its high-resolution encoder and real-time periodic error correction (RPEC).

The CEM40 stands as an exceptionally versatile and advanced mount.

Whether with or without encoders, the mount is available in two versions, both ensuring precise tracking of your optics in the night sky. The variant with high-resolution encoders (EC) on both axes achieves an impressive accuracy of less than 0.25 angular seconds and corrects periodic screw errors in real-time, eliminating the need for guiding in astrophotography.
