ongratulations on your purchase of a quality
Orion spotting scope. Your Terra spotting scope is
a high-quality optical instrument for viewing birds,
wildlife, sports events, or anything else you want to
see more closely. It will provide many years of
enjoyable viewing. Before using your Terra spotting
scope, we recommend that you read through the
following instructions.
Mounting the Terra Spotting Scope to the
Mini-tripod
The Terra Spotting scope comes complete with a mini-tripod.
This tripod will allow you to immediately enjoy using your spot-
ting scope. Attach the spotting scope to the mini-tripod by
threading the 1/4"-20 stud on the tripod into the 1/4"-20
threaded hole on the spotting scope’s body.
Using the Mini-Tripod
Once the spotting scope has been mounted to the mini-tripod,
it can be precisely aimed by the use of the altitude (up/down)
and azimuth (left/right) slow-motion knobs (Figure 1). For
large movements in altitude, loosen the altitude lock knob and
raise or lower the spotting scope to the desired level.
Retighten the altitude lock knob. For large movements in
azimuth, loosen the knurled azimuth lock ring and move the
spotting scope left or right to the desired position. Retighten
the azimuth lock ring.
Mounting the Terra Spotting Scope to an
Optional Tripod
The Terra spotting scope can also be attached to an optional
camera tripod by use of the 1/4"-20 threaded hole located on
the spotting scope’s body. This hole accepts 1/4"-20 mounting
studs that are standard on most camera tripods.
Focusing the Spotting Scope
Point the spotting scope so that it is aiming in the general
direction of an object at least 33 feet away. Turn the focus knob
(Figure 1) with your fingers until the object comes into sharp
focus. Make certain that you are turning the focus knob and
not turning the zoom eyepiece. Go a little bit beyond sharp
focus until the image just starts to blur again, then reverse the
rotation of the knob, just to make sure you’ve hit the exact
focus point.
