Using/Aligning the Red Dot Viewfinder:
The viewfinder is powered by a CR-2032 battery that is included. Before using
the viewfinder for the first time, remember to remove the plastic insulator
that is blocking the battery from connecting.
When it is time to replace the battery, remove the battery cap by loosening
the set screw. Take out the old battery and slide a new battery in place with
the positive side showing. Replace the cap, and tighten the set screw.
For the viewfinder to be effective, it must be aligned. To do this:
• Insert the 20mm eyepiece into the diagonal and power on the viewfinder by
sliding the switch on its right side to an "On" position.
• Point the eyepiece at an easy to identify target like a telephone pole that is
approximately 200 yards away. Center the object in the eyepiece. Lock the
telescope into place by tightening the panhandle.
• Without moving the telescope, position the red dot using the two
adjustment screws so that it shares the same view as the one in your
eyepiece. The front screw will move the viewfinder up and down, and the
other will move it side to side. Your viewfinder is now aligned.
Note: To preserve battery life, don't forget to turn off the viewfinder after use.
Did you know?
The magnifying power of a telescope is determined by dividing the focal
length of the telescope by the focal length of the eyepiece. This means
that as the focal length of your eyepiece increases, the magnifying power
decreases.
