INSTALLING & USING THE BARLOW LENS
Your telescope also comes with a 3x Barlow lens which triples the magnifying power of each eyepiece. To
use the Barlow lens, remove the diagonal and insert the Barlow directly into the focuser tube. Then insert an
eyepiece into the Barlow lens for viewing.
NOTE: Start by using a low power eyepiece as it will be easier to focus.
To use the moon fi lter, simply thread the fi lter to the chrome barrel of the eyepiece.
GENERAL OBSERVING HINTS
When using any optical instrument, there are a few things to remember to ensure you get the best possible image.
• Never observe through window glass. Glass found in household windows is optically imperfect, and as a result, may vary in thickness from one part of a window
to the next. This inconsistency can and will affect the ability to focus your telescope. In most cases you will not be able to achieve a truly sharp image, while in
some cases you may actually see a double image.
• Never look across or over objects that are producing heat waves. This includes asphalt parking lots on hot summer days or building rooftops.
• Hazy skies, fog and mist can also make it diffi cult to focus when viewing terrestrially. The amount of detail seen under these conditions is greatly reduced.
NOTE: Your telescope was designed for terrestrial observation as well as celestial viewing.
