Schmidt Cassegrain Telescope

Schmidt Cassegrain
Schmidt-Cassegrain telescopes are a combination of mirror and lens telescope. They combine the advantages of reflector telescopes (with high light collection power) and lens telescopes (with high-contrast imaging systems) without having their disadvantages of aberration & chromatic aberrations.
At the beginning of Tubus sits the so-called Schmidt plate (a correction plate) in the middle of the secondary mirror introduced (usually screwed) is.
Practical side effect of the Schmidt plate: The telescope is closed and thus less prone to turbulence and the tube interior is largely protected from dust.

 
A special feature of SC telescopes is that focusing does not take place via a variable focuser, but by moving the main mirror towards the focal point.
SC telescopes are very popular universal telescopes, compact in construction with high magnification, because long focal length.
 
All telescopes are checked, measured and, if necessary, adjusted before delivery. Upon request, you will receive from your telescope (from 10 "unfortunately not possible) a meaningful quality certificate (test report with star test, Ronchi, adjustment, with individual serial number) included! Please specify when ordering!
