Introduction 

 

 

Congratulations

 on your purchase of a precision-crafted 

NATIONAL GEOGRAPHIC™ 

telescope. With proper care and handling of your telescope, you will enjoy the pleasure 
of looking at nature’s wondrous sights through the eye of this instrument for many 
years. 
 
Your new Maksutov-Cassegrain telescope provides you with the clarity and contrast of 
a lens type (refractor) telescope and the brightness and color fidelity of a mirror type 
(reflector) telescope. And it all comes in an easy-to-use, compact package.  
 
As a terrestrial (land) telescope, the NG55CS delivers great views of mountains, 
valleys, wildlife, and many other wonders and features of the world around us. Its 
compact size and light weight make it an ideal telescope for hikers, travelers, cottagers, 
and anyone else who demands superior optical performance in a small telescope. 
 
As an astronomical telescope your NG55CS will reward you with excellent views of 
lunar detail, Jupiter’s four largest “Galilean” moons, and even Saturn’s rings. 
 
To obtain the best performance from your telescope, please read this manual carefully 
and completely.
