Optical telescope
An optical telescope is a telescope which is used to gather, and focus light, for directly viewing a magnified image, making a photograph, etc. The term is used especially for a monocular with static mounting for observing the sky. Handheld binoculars are common for other purposes.

Telescopes are sometimes referred to as "photon buckets" as they are used to "collect streams of photons". There are two primary types of optical telescope: reflectors (which use mirrors) and refractors (which use lenses). In addition there are compound telescopes such as the Maksutov telescope and the Schmidt-Cassegrain telescope.
