TABLE OF CONTENTS

Follow the instructions for your specific 

model in the manual. Read the entire instructions 

carefully before beginning. Your telesope should 

be assembled during daylight hours. Choose a

large, open area to work to allow room for all 

parts to be unpackaged.

B

efore you begin

Never use your telescope to look directly at the sun. 

Permanent eye damage will result. Use a proper solar 

filter for viewing the sun. When observing the sun, 

place a dust cap over your finderscope to protect it 

from exposure. Never use an eyepiece-type solar filter 

and never use your telescope to project sunlight onto 

another surface, the internal heat build-up will damage 

the telescope optical elements.
