The optical performance of your CPC telescope is directly related to its
collimation, that is the alignment of its optical system. Your CPC was
collimated at the factory after it was completely assembled. However,

To check the collimation of your telescope you will need a light source.
A bright star near the zenith is ideal since there is a minimal amount of
atmospheric distortion. Make sure that tracking is on so that you won’t

means that it moves very little thus eliminating the need to manually
track it.
Before you begin the collimation process, be sure that your telescope is
in thermal equilibrium with the surroundings. Allow 45 minutes for the
telescope to reach equilibrium if you move it between large
temperature extremes.
To verify collimation, view a star near the zenith. Use a medium to high

While your CPC telescope requires little maintenance, there are a few
things to remember that will ensure your telescope performs at its best.

for approximately two to four seconds. Then, use an optical cleaning
solution and white tissue paper to remove any remaining debris. Apply
the solution to the tissue and then apply the tissue paper to the lens.

in a dust-free environment and point it down. This will remove the
moisture from the telescope tube.
To minimize the need to clean your telescope, replace all lens covers
