10)Loosen the set screw on the star diagonal so that it does not obstruct the inner diameter of the barrel. Insert the chrome barrel of the 20mm eyepiece into the diagonal and tighten the set screw. See Figure B

11)Locate the StarPointer finderscope. Remove the knurled nuts on the threaded posts at the focuser end of the telescope tube. Mount the Star Pointer bracket by placing the bracket over the posts protruding from the tube and tightening it down with the knurled nuts. Orient the Star Pointer so that the glass window is facing towards the front of the tube.

12)Remove the lens cap from the front of the telescope.

TELESCOPE OPERATION USING YOUR TELESCOPE

Star Pointer Finderscope

The Star Pointer is the quickest and easiest way to point your telescope exactly at a desired object in the sky. It's like having a laser pointer that you can shine directly onto the night sky. The Star Pointer is a zero magnification pointing tool that uses a coated glass window to superimpose the image of a small red dot onto the night sky. While keeping both eyes open when looking through the Star Pointer, simply move your telescope until the red dot, seen through the Star Pointer, merges with the object as seen with your unaided eye. The red dot is produced by a light-emitting diode (LED); it is not a laser beam and will not damage the glass window or your eye. The star pointer is powered by a long life 3-volt lithium battery (#CR2032) located underneath the front portion of the Star Pointer. Like all finderscopes, the Star Pointer must be properly aligned with the main telescope before it can be used. This is a simple process using the azimuth and altitude control knobs located on the side and bottom of the Star Pointer. The alignment procedure is best done at night since the LED dot will be difficult to see during the day.
