Choose a conspicuous target in the distance
and place the target in the center of the field
of view of the telescope in accordance with
procedures I to III in Basic Operation.
In the illustration, a distant tower is brought
into the center of the field of view of the
telescope.
Next, look through the finder scope. You
should probably find the same target some-
where within the finder’s field of view.
In the illustration, the tower is seen in the
upper right of the finder’s field of view. The
finder scope has crosshairs.
Align the optical axis (field of view) of the
finder scope with the optical axis (field of
view) of the telescope. Adjust the finder
scope by loosening or tightening two of three
adjustment screws at a time in turn until the
target is in the same position, in the center
of the crosshairs.
In the illustration, the top of the tower is in
the center of the crosshairs.

Turn on the dot finder by turning the bright-
ness adjusting dial. There are graduations
on the dial from 0 to 11. Set the dial at 11.
The intensity of the brightness can be varied
from 1 (faint) to 11 (bright).
You will see a red dot in the center of the field
of view of the dot finder when you look along
the white guideline as shown in the Figure.
Align the optical axis (field of view) of the dot
finder with the optical axis (field of view) of the
telescope. Loosen the alignment clamp on
the dot finder and move the upper portion of
the dot finder by holding its front end until the
red dot is in the same position as the target in
the telescope. Then, tighten the alignment
clamp.
Set the brightness adjusting dial to 0 to turn
off after using the dot finder.
Place the tower in the center
of the telescope’s field of view.
