Collimation Adjustment
1
2
Collimation
is the optical alignment of your telescope's mirrors.
Your ExploraScope was collimated at the factory and should never
need to be adjusted. If for some reason the telescope is dropped or
damaged it may be necessary to adjust the alignment of the mirrors.
Do not alter the collimation unless it's necessary.
Checking the Collimation
Remove the eyepiece: rotate the focuser clockwise until the
1
eyepiece is fully extended. Rotate the chrome eyepiece barrel
counterclockwise until the eyepiece is removed.
With the eyepiece removed, look down the focuser and you will
2
see an image of the secondary mirror reflected back in the
primary mirror.
If the secondary mirror is not perfectly centered in the primary
mirror then your telescope is out of alignment. To correct this,
you must adjust the primary collimation screws located at the
rear of the tube.
