How to Collimate a Schmidt-Cassegrain Telescope

This article is a step-by-step guide on how to collimate a Schmidt-Cassegrain telescope (SCT). Like any other reflecting telescope, SCTs are vulnerable to shocks and drops causing it to go out of alignment. Therefore, collimating a SCT ensures its optimal performance. Continue reading to learn about the collimation process. Setting up for Collimation First, you […]

How to Collimate a Newtonian Reflector Telescope

Collimation determines the alignment of all components in a telescope in order to transfer light into its best focus. Newtonian Reflector Telescopes are likely to go out of alignment if they are bumped around too much or from gradual wear and tear. However, they can be re-aligned via collimation. Follow these steps on how to […]
