aligning the StarPointer FinderScoPe
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 20 mm eyepiece in installed in the focuser.
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 20 mm eyepiece and manually move the telescope until the object you chose
lies in the center 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 centered in your 20 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 a foot 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 20 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 20mm 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.
