combination giving a different telescope focal length and focal ratio. With a
secondary other than the one designed for the Cassegrain focus, the telescope
focus is usually located at a different physical position. For a telescope in an
equatorial mount plane mirrors redirect the light, with the final beam directed
along the polar axis of the telescope to the so-called Coude focus. For a telescope
in an altitude-azimuth (alt-az) mount a plane mirror directs the light along the
