The #1 Killer of Fine Optics is Bad Collimation

"Collimation" refers to the process of tweaking an optical instrument for the best possible image quality.
With regards to a telescope the term refers to the fact that the optical axes of each optical component
should all be centered and parallel, so that collimated light emerges from the eyepiece.

Have you ever noticed at Star Parties why some telescopes perform than other similar telescopes?

Collimation is the answer

Once learned, there should be no reason to ever view with an uncollimated telescope again.
