Optical tube Schmidt-Cassegrain with a diameter of 280 mm and a focal length of 2800 mm. The optics consist of a main mirror, an aspherical corrective plate, a secondary mirror and an angle cap with an eyepiece. As a rule, Schmidt-Cassegrain telescopes have shorter focal lengths than Maksutov telescopes and find more universal applications. All the more so in these telescopes it is possible to reduce the light to f / 6.3 using a special focal length reducer, which is attached to the focuser. SCT telescopes are short, relatively light, with large apertures much more practical in use than Newton telescopes. Focusing is done just like in Maksutov telescopes with the knob in the back wall of the telescope, turning the knob shifts the mirror of such a telescope forward or backward, which changes the focus position at the output of the optical tube. The telescope is equipped with the StarBright XLT system. Light transmission increases by 16% compared to traditional coatings!
