The iOptron CEM40EC is a next-level, center-balanced equatorial mount that's as functional as it is eye-catching. At a lightweight 17.4lbs, this powerhouse can handle payloads up to 40lbs – pretty amazing, right?

Next-Gen Tech from iOptron Say hello to groundbreaking features! This mount comes with an iPolar electronic polar finder scope, which ensures precise telescope alignment, even when you can't see the North Star. The quick-lock drive system has these chunky levers that let you lock in the gears effortlessly.

Versatile & Quiet Performance The CEM40EC mount sports a dual saddle that's compatible with both Losmandy and Vixen-style dovetail plates. On top of that, it operates on iOptron's whisper-quiet, energy-efficient stepper motor system for accurate tracking.

Smart Navigation Features The mount employs the Go2Nova hand controller, letting you explore over 212,000 celestial objects stored in its database. So if you're on the hunt for a mount that makes it a breeze to locate and track heavenly bodies, this one's a keeper.

Everything But the OTA This package includes a tripod, an 11lb counterweight, and the mount's computerized capabilities. Just add your own Optical Tube Assembly (OTA), and you're all set for an awe-inspiring stargazing session.

(Note: This mount is compatible with the #8027 counterweight.)
