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 until it comes into sharp focus. 

LOOK THROUGH FINDERSCOPE

Once the object is centered in your 20 mm eyepiece, look 
through the finderscope and locate the red dot.

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 20 mm eyepiece.

YOUR FINDERSCOPE IS  

 NOW  ALIGNED!

It should not require realignment unless

it is bumped 

or dropped.

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

!

CHOOSE A TARGET

Take the telescope outside during the day and find an easily 
recognizable object, like a streetlight, license plate or sign. 
The object should be as far away as possible, but at least a 
quarter mile away.
