Schmidt-Cassegrain Telescope

Schmidt-Cassegrain telescope is a Cassegrain-like two-mirror system combined with a full-aperture Schmidt corrector. Various combinations of corrector separation and mirror conics are possible, with somewhat different image field properties. Prevailing commercial arrangement is a compact design with fast spherical primary and usually also spherical secondary mirror, resulting in ~ƒ/10 system. All-spherical SCT is corrected only for spherical aberration, with low astigmatism, as well as relatively strong field curvature and coma remaining. The corrector also induces low level spherochromatism, undetectable visually and negligible for most photographic applications.
