Setting up the spotting scope
Ideally the spotting scope should be on a tripod of suitable load-bearing
capacity (Tripod included). Your spotting scope has a tripod thread to
DIN standard (5). It can therefore be attached to any tripod with a DIN
standard thread.
Important:
Remove the protective caps from the main tube and eyepiece. Make
sure they are reinserted after every use.
Controls
• Focus Knob: Look into the eyepiece (1) and rotate the focus knob
(3) in either direction to focus on an object.
• Zoom: Rotate the zoom control (2) to zoom in or out on an object;
then use the focus knob (3) to refine the focus.
4
• 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
entire main tube (4) about its own axis and thus vary the eyepiece
(1) position. To fasten the main tube in the desired position turn
the fastening screw 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 inside
and outside air, and the low quality of window glass can blur
images through the spotting scope.
• Sun shield: Extend the sun shield (9) in strong sunshine affecting
visibility. Put your hand around the spotting scope aperture ring
and simply push the shield out.

Terrestrial Observing

When viewing land objects, you will be observing through heat waves
on the earth surface. You may have noticed these heat waves while
driving down a highway during the summer. Heat waves cause a loss
of image quality.
If heat waves interfere with your viewing, try focusing at low power to
see a steadier, higher quality image. Observe in early morning hours,
before the earth has built up too much internal heat.
