Focusing the Telescope
With the 25mm eyepiece securely inserted into the correct-
image diagonal, aim the optical tube so the front (open) end
is pointing in the general direction of an object at least 1/4
mile away. With your fingers, slowly rotate the focus wheel
until the object comes into sharp focus. Go a little bit beyond
sharp focus until the image starts to blur again, then reverse
the rotation of the knob, just to make sure you’ve hit the exact
focus point.
Aligning the Finder Scope
The finder scope is used to aid in aiming the telescope. It is a
small, lower-powered telescope that sits on top of the main
telescope. Without it, it would be very difficult to aim your
Aristocrat 60mm.
The finder scope (Figure 6) must be aligned accurately with
the telescope for proper use. To align it, first aim the main tele-
scope in the general direction of an object at least 1/4 mile
away–the top of a telephone pole, tree, etc. Position that
object in the center of the telescope’s eyepiece.
Now, look in the finder scope. Is the object visible? Ideally, it
should be somewhere in the field of view. If it is not, some
coarse adjustments of the six finder scope alignment thumb-
screws will be needed to get the finder scope roughly parallel
to the main tube.
With the image in the finder scope’s field of view, you will now
use the six alignment thumbscrews to center the object on the
intersection of the crosshairs.
By loosening one alignment thumbscrew and tightening
another, you change the line-of-sight of the finder scope.
Continue making adjustments to the various alignment
thumbscrews until the image in the eyepiece is exactly cen-
tered in both the finder scope and telescope’s eyepiece.
Check the alignment by moving the telescope to another
object and fixing the finder scope’s crosshairs on the exact
point you want to view. Then look through the telescope’s eye-
piece to see if that point is centered in the field of view. If it is,
the job is done. If not, make necessary adjustments until the
two images match.
Once aligned, the finder scope should not need realignment
unless the telescope is roughly handled or jostled.
Focusing the Finder Scope
If, when looking through the finder scope, the images appear
somewhat out of focus, you will need to refocus the finder
scope for your own eyes. Loosen the lock ring located behind
the objective lens cell on the body of the finder scope (Figure
6). Back the lock ring off a few turns, for now. Refocus the find-
er scope on a distant object by threading the objective lens cell
in or out on the finder scope body. Once the image appears
sharp, lock the ring behind the objective lens cell. The finder
scope’s focus should not need to be adjusted again.
