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).
