Laser Collimator

For use with Meade's LightBridge Telescopes

Assembly

Please read the entire instruction sheet before using your Laser Collimator.

Meade's Laser Collimator simplifies the collimation process. Collimation is a method to align your telescope's optics. Your
telescope is aligned at the factory, but shipping and handling can sometimes misalign collimation. Misaligned collimation can
mean dimmer and blurrier images in your telescope eyepiece. Your instruction manual describes how to collimate your
telescope. Meade's Laser Collimator provides a simpler, second method of collimation.

Be aware of the following as you use your Laser Collimator:

Only turn on your laser when you are going to use it.
When you turn on the laser, only turn the "on screw" until the laser turns on. Do not overtighten this screw! Overtightening may
damage the collimator.

Note the small "doughnut" attached to your telescope's primary mirror. The doughnut is attached to help you perform alignment
with the Laser Collimator. When you insert the Laser Collimator into your eyepiece and turn it on, the pinpoint of laser light will
normally be close to or on top of this doughnut. However, if it is any distance away from the doughnut, perform the collimation
procedure described in your LightBridge instruction manual before you use the method described below.

DANGER: Invisible laser radiation. Avoid eye or skin exposure to direct or scattered radiation.

All lasers use up battery power very quickly and have short battery life.

STEP 1:

Remove the eyepiece or eyepiece cap from the telescope.

STEP 2:

Point the laser downward. Turn the screw on the side of the laser until the laser turns
on. Do not overtighten this screw.

STEP 6:

Go to the bottom side of the primary mirror tube and look up at the Laser Collimator.
Adjust the one, two or three of the collimation screws on the bottom, until the pinpoint
in the window (see Step #3) of the laser collimator is in the center of the window. Note
that you will have to loosen one or all of the locking screws to tighten or loosen the
collimation screws.

Return to the secondary mirror holder and readjust the tilt screws, if necessary, to make
sure the pinpoint is centered in the doughnut. Your telescope should now be aligned.
