This is not a refractor, but a Newtonian reflector telescope! Please be precise next time! I rate the telescope 4, provided 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 setup is light enough to be easily moved to other locations, for example away from artificial light sources, which have an unfavorable effect on nighttime sky observation. The image seen is bright and high-contrast.

MILITARY is a premium dealer of Celestron.
Celestron is an American company specializing in the production of optical equipment, operating continuously since 1960. From the beginning of its activity, it has developed innovative solutions supporting both amateur astronomers and professional users. It gained popularity thanks to Schmidt-Cassegrain telescopes, which set new standards in astronomical observation. Breakthrough technologies developed by Celestron include, among others, the automatic StarSense AutoAlign alignment system and the NexStar controller, which make sky observation much easier. Advanced telescopes from the EdgeHD series are also used in scientific observatories, and Fastar technology allows exceptionally fast sky imaging while maintaining high detail quality. The brand has earned recognition worldwide and is regarded as one of the leading telescope manufacturers in the mid-range segment.
