How to Use this Manual This manual is designed to instruct you in the proper use of your Celestron
C4.5 telescope. The instructions are for assembly, initial use, long term
Operation, and maintenance. There are six major sections to the manual. The
first section covers the proper procedure for setting up your Celestron C4.5
telescope.
The second section covers basic operation such as moving the telescope,
adjusting the mount, and proper balance of your C4.5. The third section
deals with the basics of astronomy. Topics include focusing, aligning the
finder, and taking your first look. The fourth section deals with the basics
of astronomy which includes celestial coordinate system, the motions of the
stars, and polar alignment. The fifth section deals with celestial photography
covering all major forms working from the easiest to the most difficult. The
last major section is on telescope maintenance, specifically on cleaning and
collimation. Keeping your C4.5 in proper collimation is the single most
important thing you can do to ensure it performs well.
The final part of this manual contains a list of objects that can be observed
through your Celestron C4.5 telescope. Included are the coordinates for each
object, its brightness, and a code which indicates what type of an object it is.
In addition, there is a list of bright stars that can be used for aligning the
setting circles. In addition to the major sections mentioned previously, there
is a list of optional accessories for your Celestron C4.5 that include a brief
description of its purpose. This is the section to consult when you've mas-
tered the basics and ready for new, more challenging observations.
Read the assembly instructions through completely before you attempt to set
up your C4.5 telescope. Then, once you've set up your C4.5, read the section
on “Basic Operation” before you take it outside and use it. This will ensure
that you are familiar with your telescope before you try to use it under a
dark sky. Since it will take a few observing sessions to familiarize yourself
with your C4.5, you should keep this manual handy until you have fully
mastered your telescope’s operation. After that, save the manual for future
reference.
A Word of Caution Your Celestron C4.5 is designed to give you hours of fun and rewarding
observations. There are, however, a few things to consider before using your
telescope that will ensure your safety and protect your eyes and your equip-
ment.
