Looking at or near the Sun will cause irreversable damage to your eye. Do not point this telescope

at or near the Sun. Do not look through the telescope as it is moving.

To use the 2x Barlow lens, remove the diagonal mirror from the eyepiece holder (17, Fig. 1). Insert the 2x Barlow lens

and secure with the thumbscrew. Next insert the diagonal mirror(15, Fig.1) and eyepiece (1, Fig. 1). Refocus until the

image is sharp.

A FEW WORDS ABOUT POWER

The useful higher magnification with any 50mm diameter telescope is in the range of 50 to 100 power. The general

rule to follow with any telescope, regarding power: Only use as much magnification as a steady, well-defined image

supports. The stability of the air varies and is one reason why having various eyepieces is desirable. Higher powers

are no guaranty of better images; in fact, the opposite is often true.

MAINTENANCE

As with any quality optical instrument, lens surfaces should be cleaned as infrequently as possible. A little dust on the

surface of the objective lens causes negligible degradation of image quality and should not be considered reason to

“clean” the lens. When lens cleaning does become necessary, use a camel’s hair brush or compressed air to gently

remove dust. Wipe only with a soft, clean cloth, applying as little pressure as possible to avoid scratching glass

surfaces. Note: Remove the dew shield/lens shade (20, Fig. 1) to access the objective lens (16, Fig. 1).
