Schiefspiegler

(type of off-axis reflecting telescope)

A Schiefspiegler telescope is an off-axis reflecting Cassegrain Reflector Reflector Telescope so the secondary mirror blocks no light to the primary. This reduces Diffraction patterns but increases Coma and astigmatism. These are often reduced through use of a long focal length.
