not damage the glass window or your eye. The Star Pointer comes equipped with a variable brightness control, two axes alignment control and mounting brackets. Before the Star Pointer is ready to be used, it must be attached to the telescope tube and properly aligned:

Star Pointer Installation

1.Slide the Star Pointer bracket into the dovetail mounting platform on top of the focuser assembly (see figure 2-6).

2.Orient the Star Pointer so that the sight tube is facing towards the front of the tube.

3.Secure the Star Pointer bracket by tightening the thumb screw on the mounting platform.

Star Pointer Operation

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. Note: Before using the StarPointer, you must first remove the

protective plastic cover over the battery (see figure 2-7).

1.To turn on the Star Pointer, rotate the variable brightness control (see figure 2-5) clockwise until you here a "click". To increase the brightness level of the red dot, continue rotating the control knob about 180º until it stops.

2.Locate a bright star or planet and center it in a low power eyepiece in the main telescope.

3.With both eyes open, look through the glass window at the alignment star.

If the Star Pointer is perfectly aligned, you will see the red LED dot overlap the alignment star. If the Star Pointer is not aligned, take notice of where the red dot is relative to the bright star.

4.Without moving the main telescope, turn the Star Pointer's azimuth and altitude alignment controls (see figure 2-5) until the red dot is directly over the alignment object.

If the LED dot is brighter than the alignment star, it may make it difficult to see the star. Turn the brightness control counterclockwise, until the red dot is the same brightness as the alignment star. This will make it easier to get an accurate alignment. The Star Pointer is now ready to be used.
