Alternate Definitions for Schmidt-Cassegrain telescopes

Term: Schmidt-Cassegrain telescopes
Definition:

A mixture of the Cassegrain telescope with a very short focal length and of a Schmidt design (due to the presence of the corrective plate), used mainly in amateur astronomy. The main advantage of this telescope is its compact design. However, Schmidt-Cassegrain telescopes produce fainter images with less contrast than other telescope designs with similar aperture sizes. This is due to the comparatively large secondary mirror required to reflect the light back the eyepiece.
