Dall-Kirkham telescope

(type of reflector telescope)

A Dall-Kirkham telescope is a type of reflector telescope that has a concave elliptical primary mirror and a convex spherical secondary. It has some aberration not present in a Cassegrain reflector or Ritchey-Chrétien telescope but is easier to grind, a tradeoff that motivates the design for some amateur telescopes.
