Optics & Image Formation: Observation, Measurement & Evidence

Astronomical optics collect electromagnetic radiation and redirect it to form images or feed instruments. Understanding image formation is necessary for choosing camera pixel size, focal length, magnification, field of view, and focus position and for diagnosing aberrations such as coma, astigmatism, or chromatic error.

A curved optical surface changes the direction of incoming rays so rays from a given sky direction converge near a corresponding point in the focal plane.
