    14. NATS 1311 - From the Cosmos to Earth Two Fundamental Properties of a Telescope Resolution smallest angle which can be seen ? = 1.22 ? / D The angular resolution of a reflecting telescope is dependent on the diameter of the mirror (D) and the wavelength of the light being viewed (?) Light-Collecting Area think of the telescope as a “photon bucket” The amount of light that can be collected is dependent on the mirror area A = ? (D/2)2 These properties are much more important than magnification which is produced by placing another lens - the eyepiece - at the mirror focus. Astronomers do not look through telescopes with their eyes - a light gathering detector (for instance a camera) records the image which can later on be magnified to any desired size.
