Aligning the
Finderscope
The finder is one of the most important parts of your
telescope. It helps you locate objects and center
them in the eyepiece. The first time you assemble
your telescope, you need to align the finder to the
telescope's main optics. It's best to do this during
the day*.
*SOLAR WARNING! Never attempt to view
the Sun through any telescope without a
proper solar filter!

LOOK THROUGH FINDERSCOPE
Once the object is centered in your 25mm eyepiece,
look through the finderscope and locate the red dot.

1
CHOOSE A TARGET
Take the telescope outside during the day and find
an easily recognizable object, such as a streetlight,
car license plate or sign. The object should be as far
away as possible, but at least a quarter mile away.
4
ADJUST THE FINDERSCOPE
Without moving the telescope, use the two
adjustment knobs to move the finder around until
the red dot appears over the same object you are
observing in the telescope's 25mm eyepiece.
2
CENTER THE TARGET IN THE EYEPIECE
Look through the telescope using your lower
powered eyepiece. 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
on either side of the telescope until it comes into
sharp focus. NOTE: The image in your telescope
may appear inverted. This is perfectly normal in an
astronomical telescope.

YOUR FINDERSCOPE IS NOW ALIGNED!
It should not require realignment unless it is bumped
or dropped.
