Welcome to the Celestron world of amateur astronomy! For more than a
quarter of a century, Celestron has provided amateur astronomers with the
tools needed to explore the universe. The Celestron CM-1100 and CM-1400
continues in this proud tradition combining large aperture optics with ease of
use and portability. With a mirror diameter of 11 inches, your Celestron CM-
1100 has a light gathering power of 1,593 times that of the unaided human eye,
and the CM-1400 has a light gathering power of 2,581 times that of the unaided
human eye. Yet despite their large apertures, the Celestron CM-1100 and CM-
1400 optical systems are extremely compact and portable because they utilize
the Schmidt-Cassegrain design. This means you can take your Celestron CM-
1100 or CM-1400 to the mountains or desert or wherever you observe.
The Celestron CM-1100 and CM-1400 are made of the highest quality materials
to ensure stability and durability. All this adds up to telescopes that will give
you a lifetime of pleasure with a minimal amount of maintenance. And, your
Celestron CM-1100 and CM-1400 are versatile — they grow as your interest
in astronomy grows.
Your Celestron CM-1100 and CM-1400, are not limited to astronomical viewing
alone. They can also be used for terrestrial viewing to study the world around
you. All you need to do is take the time to familiarize yourself with your
Celestron telescope and its operation.
NOTE
The CM-1100 and CM-1400 share the same mount and are basically the
same with the exception of the larger aperture of the 14". So, this
manual will basically discuss the CM-1100 but will discuss the CM-1400
when there are differences. Users of the CI-700 mount by itself will find
complete assembly and operation instructions in the "AssemblingYour
CM-1100" and "Using the Drive" sections of this manual.
