COLLIMATION
The optics of the telescopes are aligned correctly at Vixen's factory before shipment. It is rare that telescopes
go out of alignment, unless its tube is knocked strongly. Please contact a Vixen dealer in your area for repair or
re-collimating if your Vixen telescope is out of collimation.

Select a second- or a third-magnitude star and place it the center of the telescope's field of view by using
a moderately high power eyepiece. Focus the star precisely. And then defocus slightly and you will look
for striped patterns that surround the star. If the striped pattern can be seen as a concentric image, your
telescope is properly aligned.
