ALIGNING THE FINDERSCOPE

The fi nderscope helps you aim your telescope by looking through the fi nderscope windows and lining up the two central 
dots with your target. 

The fi rst time you assemble your telescope, you need to align the fi nderscope with the main optics of the telescope.  
Although this step can be done out in the fi eld at night, it is signifi cantly easier outdoors in daylight.  Once you have 
completed the fi nderscope alignment, you should not have to repeat this step unless the fi nderscope is bumped.

1.   With the 20 mm eyepiece installed, take the telescope outside during the day. Using your naked eye, fi nd an easily 

recognizable object, such as a streetlight, car license plate, or tall tree. The object should be as far away as possible, 
but preferably at least a quarter mile away.

2.  Position the telescope so that it is roughly pointing toward the object you chose in step 1. 

3.   Look through the telescope and manually move it 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 mirror reversed left to right. This is normal in an astronomical telescope.

4.  Turn on the fi nderscope by fl ipping the red toggle switch.

5.   Looking through the fi nderscope you should see two dots surrounded by two circles fl oating in the fi eld of view.  

Position your head behind the fi nderscope so that the two dots merge and appear as one and the two circles appear 
concentric.  Now look for your target in the background.  The dot will probably be close to, but not on top of, the 
object you see when you were looking through the 20 mm eyepiece.  

6.   Without moving the telescope, use the two thumb screws on the top of the fi nderscope to move the rear dot until 

both dots appear 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 window and place the red 
dots on the target you are trying to view and verify that it is visible in the 20 mm eyepiece of the scope.  

With your fi nderscope aligned, your telescope is fully assembled and you are ready to observe! 

NOTE: 

Be sure to turn off the fi nderscope when not in use to conserve battery power.
