ing the power switch to ON (refer to

Figure 18). The “1”

position provides dim illumination while the “2” position
provides brighter illumination. Typically the dimmer setting
is used under dark skies and the brighter setting is used
under light-polluted skies or in daylight. Position your eye
at a comfortable distance from the rear of the unit. Look
through the rear of the finder scope with both eyes open
to see the illuminated red dot. The target object should
appear in the field of view somewhere near the red dot.

4. You’ll want to center the target object on the red dot. To do

so, without moving the telescope, use the finder scope’s
vertical and horizontal adjustment knobs (shown in

Figure

18) to position the red dot on the object.

5. When the red dot is centered on the distant object, check

to make sure the object is still centered in the telescope’s
eyepiece. If it isn’t, re-center it then adjust the finder

scope’s alignment again. When the object is centered in
the telescope eyepiece and on the finder scope’s red dot,
the finder scope is properly aligned with the telescope.
The red dot finder scope’s alignment should be checked
before every observing session.

At the end of your observing session, be sure to slide the
power switch on the red dot finder scope to OFF to preserve
battery life.
