Collimation — Optical Alignment

  • Michael W. Swanson
Part of the Patrick Moore’s Practical Astronomy Series book series (PATRICKMOORE)


Collimation is the process of aligning all the optical components of a telescope so that the focal plane of the telescope meets the focal plane of the eyepiece squarely. With any telescope there are many potential sources for misalignment, but only a limited number of components are easily adjusted. In fact, some telescopes do not have any user adjustments at all. These scopes are collimated at the factory or the design of the telescope itself insures collimation.
