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
TM
. 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
TM
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
®
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.
