echnical Support 

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.
