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 . Remember to always turn the
power off after you have found an object. This will extend the life of both the battery
■■■ and the LED
The 102mm AZ comes with a 6x30 finderscope that attaches to a dovetail mounting
platform on the focuser assembly. The finderscope has a spring-loaded adjustment
screw that puts pressure on the finderscope while the remaining screws are used to
adjust the finder horizontally and vertically. To install the finderscope onto the
telescope you must first mount the finderscope through the finder bracket and then
attach it to the telescope.
1. Slide the rubber O-ring over the eyepiece end of the finderscope and roll it
2/3 of the way up the finderscope.
2. Insert the eyepiece end of the finderscope through the bracket until the O-
ring presses tightly between the finder and the inside of the bracket.
3. Tighten the adjustment screws until they make contact with the finderscope
body.
To align the finderscope:
1. Choose a target that is in excess of one mile away. This eliminates any possible
parallax effect between the telescope and finder.
2. Center your target in the main optics of the telescope. You may have to move
the telescope slightly to center it.
3. Adjust the screw on the finder bracket that is on the right (when looking
through the finder) until the cross hairs are centered horizontally on the target
seen through the telescope.
4. Adjust the screw on the top of the finder bracket until the cross hairs are
centered vertically on the target seen through the telescope.
Image orientation through the finder is inverted (i.e., upside down and backwards
left-to-right). This is normal for any finder that is used straight-through.
