ALIGNING THE RED DOT FINDERSCOPE
The fi nder is one of the most important parts of your
telescope. It helps you locate objects and center them
in the eyepiece. The fi rst time you assemble your
telescope, you need to align the fi nder 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 fi lter!

LOOK THROUGH
FINDERSCOPE
Once the object is centered in your 20mm eyepiece,
look through the fi nderscope and locate the red dot.
BALANCING THE TELESCOPE
To eliminate undue stress on the mount and gears, the telescope should be properly balanced on the mount .
To balance the mount in the RA axis:
1 Make sure the telescope is properly attached to the mount with the dovetail mounting knobs tightly secured .
2 Release the RA clutch knob to allow the scope to spin freely in the RA axis .
3 Rotate the telescope in the RA axis so that the telescope tube is on the side of the mount and the counterweight bar is parallel to the ground .
4 Slowly release your grip on the telescope and see what side is heavier – the side with the telescope tube or the side with the counterweight .
5 If the counterweight side is heavier, loosen the counterweight locking knob and slide the counterweight up the shaft (toward the telescope
tube) a small amount, lock the counterweight down in its new position and try the test again .
6 If the telescope tube side is heavier, loosen the counterweight locking knob and slide the counterweight down the shaft (away from the
telescope tube) a small amount, lock the counterweight down in its new position and try the test again .
7 Keep adjusting the position of the weight until you can let the telescope go and it does not move up or down .

CHOOSE A TARGET
Take the telescope outside during the day and fi nd 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.

ADJUST THE FINDERSCOPE
Wit h o ut m o ving t he t ele s cop e, use the two
adjustment knobs to move the fi nder around until
the red dot appears over the same object you are
observing in the telescope's 20mm eyepiece.

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 astronomical
telescopes.
