| Dall-Kirkham Telescope |
A form of Cassegrain telescope in which the profile of the primary mirror is ellipsoidal rather than the more usual paraboloid. A spherical mirror is used for the secondary. The resulting field of view is considerably smaller than that of a conventional Cassegrain telescope of the same size.
