1. CEM40 Introduction

The iOptron

CEM40 mount is the next generation of center-balanced equatorial mounts. This mount is

incredibly eye-pleasing, and its beauty is found in more than its appearance. The functionality of the

mount is superb. Weighing in at only 15.8lbs., this mount can support a payload of up to 40lbs! That's

incredible!

This mount also has an integrated electronic polar finder scope known as the iPolar. This tool ensures

the accurate alignment of a telescope, even when the pole star is obscured. There are large levers on

the quick-lock drive engagement system; these large levers make it easy to snap the gears into place.

Make way for an innovative mount! This iOptron CEM40 mount uses iOptron's patent-pending

Universal Self-Centering Saddle (USCS). This saddle accommodates Losmandy and Vixen-style

dovetail plates. The CEM40 also uses iOptron's ultra-quiet, low-power consumption stepper motor drive

system, aiding the mount in providing precise tracking.

The iOptron CEM40 mount uses the Go2Nova® 8407 hand controller to navigate the night sky. This

incredible technology helps observers find celestial objects with the aid of the mount's 212,000+ object

database! For those looking for a telescope that has the capability of tracking and finding beautiful night

sky objects, this mount is a must have tool.
