Move the main tube (horizontally)
Your spotting scope has a tube clamp (mobile centre ring) with fas-
tening screw. Turn that screw counter-clockwise to undo the main
tube clamp. You can then turn the tube about its own axis. The
desired viewing position can thus be set. To fix the main tube in
place turn the fastening screw clockwise.
Focussing, zoom function
The Dachstein spotting scope has a double focussing wheel for
coarse and fine setting (10:1 gearing).
Align the spotting scope to a target about 50 to 100 m away, slow-
ly turn the focussing wheel (large=coarse focus) until the image is
correctly focussed. To finely adjust focussing use the smaller wheel.
Turn the zoom lens and change focus slowly upwards. Focus cor-
rection is essential.
When zooming in or out always correct the focus with the wheel.
Indoor Viewing vs. Outdoor Viewing
Although you may casually observe through an open or closed win-
dow, the best observing is always done outdoors. Temperature dif-
ferences between inside and outside air, and the low quality of win-
dow 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.
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.
Cleaning and Maintenance
Your spotting scope is a precision optical instrument designed for a
lifetime of rewarding viewing. It will rarely, if ever, require factory
servicing or maintenance. Follow these guidelines to keep your
spotting scope in the best condition:
•
Avoid cleaning the spotting scope's lenses. A little dust on the
front surface of the spotting scope's correcting lens will not
cause loss of image quality.
•
When absolutely necessary, dust on the front lens should be
removed with very gentle strokes of a camel hair brush or
blown off with an ear syringe (available at most pharmacies).
•
Fingerprints and organic materials on the front lens may be
removed with a solution of 3 parts distilled water to 1 part
