1. Choose a conspicuous target in the distance and place the target
in the center of the field of view of the telescope. (In the
illustration, a distant tower is brought into the center of the field of
view of the telescope.)
2. Next, look through the finder scope. You should probably find the
same target somewhere within the finder's field of view.

3. Align the optical axis (field of view) of the finder scope with the
optical axis (field of view) of the telescope.
scope by loosening or tightening the adjustment screws A and B
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.)

Magnification of the Telescope
When using an eyepiece with shor t focal length (small
number in millimeters), the image will be dim and the range
of sharp focus will be small.
The image will be harder to see so begin with an eyepiece
with long focal length (low magnification).
Dividing the focal length of the telescope by the focal length
of the eyepiece gives the magnification.
