Main article: List of telescope types

Telescopes are broadly classified into two main types.

Optical telescopes
Radio telescopes

Optical telescopes are also divided into two types.

Galilean refracting telescopes
Newtonian reflecting telescopes

Galilean or refracting telescopes employ the refractive properties of light, and are constructed of lenses. These can be used for both terrestrial and astronomical viewing.

Newtonian or reflecting telescopes employ the reflective properties of light, and use mirrors and lenses. These are more useful for astronomical viewing.
