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! iOptron CEM40G mount has a built-in iGuider

guiding camera. The

mount has a 6” dual saddle that 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.
