• Moving the main tube:
These spotting scopes have a main
tube clamp (6) and fastening screw
(7). Turn screw (7)
counter-clockwise to undo the main
tube clamp. You can then turn the en-
tire main tube (4) about its own axis
and thus vary the eyepiece (1) posi-
tion. To fasten the main tube in the
desired position turn the fastening
screw (7) clockwise.
• Indoor Viewing vs. Outdoor
Viewing:
Although you may casually observe
through an open or closed window,
the best observing is always done
outdoors. Temperature
differences between indoor and out-
door air, and the low quality
of window glass can blur images
through the spotting scope.
• Sun shield:
Extend the sun shield (8) in strong
sunshine affecting visibility. Put your
hand around the spotting scope
aperture ring and simply push the
shield out. But you should never look
at or near the sun! To find out more
read the warnings in this manuals.
Observing land objects
When viewing land objects, you will
be observing through heat waves
on the earth surface. You may have
noticed these heat waves when dri-
ving down a highway with mom and
dad during the summer. Heat waves
cause a loss of image quality.
If heat waves interfere with your vie-
wing, try focusing at low power to
see a steadier, higher quality image.
Observe in early morning hours, be-
fore the earth has built up too much
internal heat.
