Optical tube Schmidt-Cassegrain with a mirror diameter of 235 mm and a focal length of 2350 mm - its optics consist of a main mirror, aspherical correction plate, secondary mirror and an angle cap with eyepiece.
The tube weighs 9.1 kg and is 559 mm long - considering the considerable aperture it is still a fairly handy telescope.
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!
This telescope allows for very advanced observations of the Moon and planets, while under a dark sky it will show numerous deep sky objects such as open clusters, globular clusters, planetary nebulae and bright galaxies. The tube is equipped with a dovetail rail in the Vixen / CG-5 standard. Also included is the mirror angle attachment, 6x30 optical finder and 25mm 1.25 "eyepiece.
