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. As such, it is also a variation on Schmidt camera. 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.
