2. Checking the alignment of the EZ Finder is easiest during the day. Look along the telescope’s
tube to point the telescope in the general direction of an object ON THE GROUND such as a
distant streetlight, top of a chimney, or a distant mountain peak.
3. Turn on the EZ Finder using the power knob and turn the dial until the red dot is visible. The
intensity of the dot can be adjusted by turning the power knob. Use the dimmest possible
setting that allows you to see the dot without difficulty.
4. Move the telescope so that the red dot is centered on the object.
5. The object should be in the eyepiece or right outside of its field of view.
If it is not centered
a. First center the object in the eyepiece.
b. Without moving the telescope, use the vertical and horizontal adjustments on the finder
scope to center the red dot on the object.
6. Use the EZ Finder to point the telescope at the object in the sky you wish to view.
7. When not in use and at the end of your observing session, be sure to turn the power knob
counterclockwise until it clicks off!
Don’t see a red dot while the power knob is on? To change battery, remove the cover from
the finder and replace the coin-type CR2032 battery using the spare found in the gear bag.
