Cem70 Introduction - iOptron CEM70 Instruction Manual

1. CEM70 Introduction

Welcome to a new type of equatorial mount – the iOptron
or CEM! CEM70 mount offers the benefits of our revolutionary "center balance" design: stability,
accuracy, and smooth mechanical operation, while capable of carrying a payload up to 70 lbs (31.8 kg).
The "center balance" design's natural stability is due to its focusing the mount along with payloads
weight directly over the center of the pier or tripod.
The CEM70's performance is demonstrated by its low periodic tracking error: <±3.5 arc
seconds. Along with the stability aspect, the CEM70 features an advanced cable management system
consisting of more ports in more locations preventing tangle ups and reducing the chance of fractured
cables.
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.
The CEM70 family currently has two versions: CEM70 standard version (#C70A) and CEM70G
(#C70AG). The CEM70G mount has an iGuider built-in autoguiding system, USB 3.0 connection and
WIFI connection.
The CEM70 mount is equipped with the most advanced GOTONOVA
making it one of the most powerful and accurate GOTO mounts available. TheGo2Nova
controller has a database of over 212,000 objects making it easy to locate even the faintest celestial
objects.
