Tele Vue Starbeam advanced telescope pointer - Manual (Page 2)

You must remember to switch off the illuminator when not in
use to avoid draining the battery.
Alignment & Use:
1) Thread Illuminator into Starbeam. Compression of the rubber O-ring allows convenient positioning of the Blink Adjustment Knob.
2) Turn on Illuminator by rotating the black knob on the end clockwise. Continuing to rotate the knob clockwise increases the brightness.
Adjust the intensity of the illuminator so the red-star appears comfortably bright without disturbing your night vision.
Rotate the white Blink Adjustment Knob on the side of the housing to adjust the pulse rate of the LED. Rotate the knob fully clockwise
for continuous on.
3) At 50x to 100x, place a star in the middle of your telescope field.
4) To view through the Starbeam locate your eye above the Illuminator and a foot or two back from the beamsplitter. Even though
you can be further back or off to the side a little and still see the "red-star," it is easiest to first see the dot in this straight through position.
While viewing through Starbeam, use the horizontal and vertical adjustment screws to overlay the "red-star" onto a test star in the sky. That's
it!
To raise or lower Starbeam, loosen the Lock Screw and turn the Vertical Adjustment Screw. Starbeam will pivot vertically on the
Horizontal Adjustment Screws. The Lock Screw works "against" the Vertical Adjustment Screw to lock the assembly. It is only
necessary to lightly snug the Optical Assembly Support Bar against the Lock Screw. Tightening it too much will interfere with horizontal
movement.
The Horizontal Adjustment Screws are meant to work against each other. Loosening one Horizontal Adjustment Screw while
tightening the other moves Starbeam smoothly in the horizontal plane. The Lock Screw acts as a pivot for this horizontal adjustment. The
movements sound complicated but in practice are easy to do.
Once aligned to your scope and locked, Starbeam should not need further adjustment. Incidentally, Starbeam is prefocused (collimated)
and designed so that little image shift is visible between a real star seen through the Beamsplitter Mirror/Lens and the projected "red-star"
overlaying it.
To use the Flip-Mirror, simply tilt it back until you can see the reflection of the Beamsplitter Mirror/Lens in the Flip Mirror as the diagram
below illustrates.
Care:
Although Starbeam has a durable anti-reflection coating on the convex outside (sky side) surface, if dew occurs, it's best to use a dew-
zapper or hair dryer gun to warm the dew away.
There is no coating on the inside (concave) surface of the mirror lens so cleaning is especially easy.
Starbeam is made of precision CNC machined aluminum, black-anodized for a lifetime of field use and needs no special care to maintain
its fine finish.
When it is time to replace the battery, use a Duracel XL DL 1/3N lithium or equivalent battery. To install, pull the white Blink Adjustment
Knob out from the side of the Illuminator. Gently pull out the electronic assembly by holding the ON/OFF Brightness Control Knob. Take
note of the polarity of the battery. The negative (-) side is toward the LED. Insert the new battery into the receptacle in the same orientation
as the old one. Installing the battery with the polarity reversed will damage the circuitry and void the warranty. Remove the anti-
rattle foam from the old battery and press it on to the new battery. Compress the foam and slide the electronic assembly into the Illuminator
housing. You may have to rotate the circuit board to get the LED to slip into the hole in the front end and also to align blink potentiometer
with the hole in the housing. Insert the white Blink Adjustment Knob through the side of the body and into the hole on the potentiometer.
Starbeam helps you find your celestial favorites quickly and easily with any scope. We wish you years of pleasure with it.
