2. Zoom
3. Focus wheel, focus ring
4. Optical tube
5. Tripod adapter thread
Setting up the spotting scope
Ideally the spotting scope should be on a tripod of suitable load-
bearing capacity (obtainable as a Bresser accessory). 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.
• 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.
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).
