COMPUTERIZED TELESCOPE
STARPOINTER OPERATION
The StarPointer finderscope helps you aim your telescope by looking through its round glass window
and covering your target with the red dot projected in the window. The first time you assemble your
telescope, you’ll need to align the StarPointer with the main optics of the telescope. Although this step
can be done at night, it is significantly easier during the day. Once you have completed the finderscope
alignment, you should not have to repeat this step unless the finderscope is bumped or dropped.
TO ALIGN THE STARPOINTER:
1. Take the telescope outside during the day. Using your naked eye, find an easily recognizable object,
such as a streetlight, car license plate, or tall tree. The object should be as far away as possible, but at
least a quarter mile away.
2. Remove the main dust cover from the telescope and make sure your 25 mm eyepiece in installed.
3. Move the telescope left and right or up and down so that it is roughly pointing toward the object you
chose in step 1.
4. Look through the telescope using your 25 mm eyepiece and manually move the telescope until the
object you chose lies in the centre of the view. If the image is blurry, gently turn the focus knobs until
it comes into sharp focus.
NOTE: The image in the telescope eyepiece will appear upside-down. This is perfectly normal in an
astronomical telescope.
5. Once the object is centreed in your 25 mm eyepiece, turn on the finderscope by turning the power
switch knob clockwise as far as it will go.
6. With your head positioned about 30 cm (1 ft) behind the finder, look through the round window and
locate the red dot. It will probably be close to, but not on top of, the object you see when you are
looking through the 20 mm eyepiece.
7. Without moving the telescope, use the two adjustment knobs on the side and underneath the StarPointer.
One controls the left-right motion of the dot, while the other controls the up-down motion. Adjust both
until the red dot appears over the same object you are observing in the 25 mm eyepiece. Now choose
some other distant targets to practice aiming your telescope. Look through the StarPointer window
and place the red dot on the target you are trying to view and verify that it is the 25 mm eyepiece of
the scope.
With your StarPointer finderscope aligned, your telescope is fully assembled and you are
ready to observe!
NOTE: Be sure to turn off the StarPointer finderscope when not in use to conserve battery power.
