1.
Slide the Star Pointer bracket into the dovetail mounting platform on top of the
focuser assembly (see figure 2-9).
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.
1.
Before using the StarPointer, you must first remove the protective plastic cover over the battery (see figure 2-10).
2.
To turn on the Star Pointer, rotate the variable brightness control (see figure 2-8) 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.
3.
Locate a bright star or planet and center it in a low power eyepiece in the main telescope.
4.
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.
5.
Without moving the main telescope, turn the Star Pointer's azimuth and altitude alignment controls (see figure 2-8) until
the red dot is directly over the alignment object.
