2. Slide the mounting track at the bottom of the Star Pointer over the dovetail portion of the bracket. It may be necessary to

loosen the two screws on the side of the mounting track before sliding it over the dovetail. The end of the Star Pointer with

the glass window should be facing out towards the front of the telescope.

3. Tighten the two screws on the side of the mounting track to secure the Star Pointer to the dovetail bracket.

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. To turn on the Star Pointer, rotate the variable brightness control (see figure 3-3) 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. Remember to

remove the plastic cover over the battery, and always turn the power off after you have found an object. This

will extend the life of both the battery and the LED.

Glass Window

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.

4. 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 until the red dot is

directly over the alignment star.

If the LED dot is brighter than the alignment star, it may make it difficult to see the star. Turn the variable 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.

Removing the Optical Tube

The NexStar SE dovetailed quick release bracket that allows you to adjust the optical

tube for proper balancing or remove the tube for safe storage. To adjust or remove the

tube from that base, simply loosen the quick release clamp knob (see figure 3-4) and

slide the tube back towards the rear cell of the tube.
