STEP 5:
Using a Philips head screwdriver, adjust the one, two or all three tilt screws on the
secondary mirror holder until the the laser pinpoint is in the center of the doughnut.
Notice that when the pinpoint is on top of the doughnut that the pinpoint brightens con-
siderably. When it is in the center, it dims again.
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.
STEP 7:
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.
