II. Aligning the Finder Scope
IV. Focusing the Finder Scope
It is very difficult for the telescope user to locate a target object through the telescope’s field of view at
high magnification, especially as the field of view narrows. The use of a finder scope will make it much
easier. Be sure to align the finder scope with the telescope’s field of view before you start observing.
III. Adjusting the Illuminated Reticle
③
While looking through the finder scope, align the field
of view with the telescope’s field of view by loosening
or tightening the adjustment screws on the finder
bracket so that the target comes close to the center
of the field of view.
Low-profile Finder Bracket
In the case of the low-profile 50mm finder bracket,
the top of the tower can be moved toward the center
of the cross hairs by loosening the adjustment screw
C and then tightening the adjustment screws A and B.
XY Finder Bracket
In the case of the 50mm XY finder bracket, the top of
the tower can be moved toward the center of the
cross hairs by loosening the adjustment screw A and
then loosening the adjustment screws A.
The finder scope is adjusted to focus at infinity at
Vixen’s factory before shipment. Because the ability of
vision differs with individual persons, it is possible that
you will need to readjust the focus of your 7x50 finder
scope with illuminated reticle. Following is the procedure.
①
②
While looking through the finder scope, turn the rim of
the finder scope’s eyepiece to left or right by hand to
bring the crosshairs reticle into focus.
While holding the lock ring next to the objective lens
cell of the finder scope, turn the objective lens cell so
that it loosens. Find a position of the objective lens
cell that brings a distant view into focus. Tighten the
objective lens cell with the lock ring at that position.
Do not loosen the objective lens cell too much as it
may detach from the finder scope.

Brightness of the illuminated reticle varies gradually
as you turn the brightness adjustment dial. The dial
will return to the “off” position if you continue turning.
Stop turning the dial at the brightness appropriate for
your viewing.
Be sure to turn off the brightness adjustment dial if it
is not in use. The illuminated reticle goes off when
the dot mark on the side of the dial is aligned with the
dot mark on the body.

Choose a conspicuous target in the
distance (over 200m away) and place the
target in the center of a field of view of the
telescope. The image in the telescope’s
field of view is usually upside down.
Next, look through the finder scope. You
should probably find the same target
somewhere 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 cross hairs.

③
Slide the rubber O ring onto the eyepiece
end of the finder scope as shown in the
figure.
There are two grooves on the finder scope
tube. Position the O ring about 6mm short
of the narrow groove at the middle of the
finder scope tube. Straighten the O ring if
it is twisted.
Loosen the two adjustment screws on the
finder bracket ring as shown in the figure
so that the tip of the screws are
completely moved back to allow passage
of the finder scope tube.
※
Do not touch the fixed stud on the bracket
ring as it is a spring-loaded adjuster.
④
Slide the finder scope tube into the
bracket ring from its eyepiece end as
shown in the figure 4-1 until the O ring
touches the rim of the bracket ring.
Note1:
Make sure that the brightness adjustment
dial is positioned conveniently before you
slide the finder scope tube into the bracket
ring.
Note2:
Take care not to scratch with the tip of the
adjustment screws when you slide the
finder scope tube into the bracket ring.

Push the O ring together with the finder
scope tube into the bracket ring until the O
ring fits snugly. Confirm that the finder
scope tube is not pushed back by the
rubber O ring.
Tighten the two adjustment screws
gradually so that the finder scope tube is
securely set in the bracket ring. Mount
the finder scope unit equipped with the
finder bracket on your telescope.
