• The inclusion of an additional eyepiece – 10mm. This gives you two additional powers with your telescope – 70mm and 210 (using
the Barlow
Lens).

The Star Pointer comes equipped with a variable brightness control, two axes alignment control and mounting bracket. Before the Star Pointer is ready to be used, it must be
attached to the telescope tube and properly aligned.
1. Remove the knurled nuts on the threaded posts on the optical tube (see Figure 2-17 in the instruction manual).
2. Mount the Star Pointer by placing the holes in the bracket over the posts protruding from the optical tube and then holding it in place thread on the knurled nuts and
tighten them down.
3. Note that the Star Pointer should be oriented so that the Sight Tube is facing toward the front of the optical tube.

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 image at left below).
2. To turn on the Star Pointer, rotate the variable brightness control 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 image at right below) 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.
