iOptron CEM120 - CEM120 Introduction; Key Features and Design

1. CEM120 Introduction
Welcome to a new type of equatorial mount – the iOptron
®
Center-Balanced Equatorial Mount,
or CEM! It offers the benefits of our revolutionary “center balance” design: stability, accuracy, and
smooth mechanical operation, while capable of carrying a payload up to 115 lbs (52 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 CEM120's performance is demonstrated by its low periodic tracking error: <±3.5 arc
seconds for CEM120 and <0.15 arcsec RMS for CEM120EC/CEM120EC2. Along with the stability
aspect, the CEM120 features an advanced cable management system consisting of more ports in more
locations preventing tangle ups and reducing the chance of fractured cables. It also adds some new
features to the CEM family like Wi-Fi and LAN for remote operation and easy to use, reliable clutches
on both axes.
The CEM120 family has three versions: CEM120 standard version (#7300), CEM120EC
(#7301) with high precision optical encoder on RA axis, and CEM120EC2 (#7302) with high precision
optical encoders on both RA and DEC axes.
The CEM12 mount is equipped with the most advanced GOTONOVA
®
GOTO technology,
making it one of the most powerful and accurate GOTO mounts available. TheGo2Nova
®
8407+ hand
controller has a database of over 212,000 objects making it easy to locate even the faintest celestial
objects.
