Bresser Spotty 20 Mode D'emploi page 9

• 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 enti-
re 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 (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 sun-
shine 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 war-
nings 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 driving down a
highway with mom and dad during the
summer. Heat waves cause a loss of
image quality.
If heat waves interfere with your view-
ing, try focusing at low power to see a
steadier, higher quality image. Obser-
ve in early morning hours, before the
earth has built up too much internal
heat.
