Schmidt-Newton Telescope

(Schmidt-Newtonian Telescope)
(type of reflecting telescope)

A Schmidt-Newton Telescope is a variation on a Newtonian Telescope, where the light first passes through a lens (Schmidt corrector plate), which compensates somewhat for spherical Aberration. Such a telescope can have less Coma than a Reflector Telescope using a parabolic mirror such as a Newtonian, which makes shorter focal lengths useful. The presence of a lens the size of the Aperture and Primary Mirror limits the size of such a telescope.
