Uses lenses to form an image. Typically used for lunar, planetary, and binary star observations.

Twin telescopes mounted side-by-side and aligned to point accurately to the same point in the sky. Offers 3D-like depth perception and is useful for wide-field observations such as open star clusters and comets.

Uses a single or a combination of curved mirrors that reflect light and form an image. Commonly utilized for deep sky observations.

Operates from outside of Earth's atmosphere. Provides a clearer view of the cosmos, free from atmospheric distortions. Hubble Space Telescope is a prime example, used for high-resolution imaging across various wavelengths.

Uses a combination of a spherical primary mirror and a Schmidt corrector plate to form an image. Well-suited for astrophotography and detailed observations of celestial bodies.

Specifically designed for observing the Sun. Usually has special filters to protect against the intense sunlight. Often used to study solar phenomena like sunspots, flares, and eclipses.

A type of reflecting telescope with a simple mount that makes it easy to operate. Popular for visual observation of deep-sky objects due to its portability and affordability.
