TRAVELSCOPE 60 | 5
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 eyepiece from the daigonal and place the
Barlow lens between the diagonal and the eyepiece.
NOTE: Start by using a low power eyepiece as it will be easier to focus.
To use the Moon filter, simply thread the filter to the chrome barrel of the eyepiece.
FOCUSING
To focus your Travel Scope, turn the focus knob near the rear of the telescope.
NOTE: Remove the Travel Scope’s front lens cap prior to observing.
NOTE: If you wear glasses, you may want to remove them when observing with an eyepiece attached to the telescope. However, if you have astigmatism, corrective lenses should be worn at all times.

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 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. In some cases you
may 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 difficult to focus when viewing land-based objects.. The amount of detail you can see under these conditions is greatly
reduced.
NOTE: Your telescope was designed for observing both land-based and celestial objects.
