This is not a lens refractor, but a Newtonian mirror telescope! Next time, please be correct! And I give the telescope 4 stars (if the optics and mechanics are good).
Achromatic refractor with an objective lens diameter of 130 mm and a focal length of 650 mm.
This refractor telescope gathers 238x more light than the human eye at night. It is mounted on an equatorial mount, and the whole set is light enough to allow easy movement to other locations, for example away from artificial light sources that have an adverse effect on night sky observation. The viewed image is bright and high-contrast.

Militaria.pl is a premium dealer of Celestron.
Celestron is an American manufacturer of optical equipment that has been developing and refining solutions in amateur and professional astronomy since 1960. The brand became famous thanks to Schmidt-Cassegrain telescopes, and its innovative solutions, such as the StarSense AutoAlign automatic alignment system and the NexStar controller, significantly changed the way night sky observations are conducted. Celestron EdgeHD telescopes are also used in professional observatories, and Fastar technology enables ultra-fast sky imaging. The company has gained international renown and has become one of the most important manufacturers in the mid-range telescope segment.
