Visit Telescope K100 Klevtsov-Cassegrain is a compact, high-performance telescope designed to deliver excellent image quality while maintaining compact dimensions. Thanks to its ingenious optical design, it combines primary and secondary mirrors with a sub-aperture corrector lens, enabling the focal length to be “folded” into a short, easily transportable tube.
With a diameter of 100 mm and a focal length of 1000 mm (f/10), this telescope is particularly suitable for observing double stars, details of the lunar surface and bright planets. Its optical design ensures sharp, high-contrast, well-defined images, ideal for high-magnification observations.
The primary and secondary mirrors are treated with a special Radiant™ Aluminum Quartz (RAQ™), offering up to 94 % reflectivity. This technology guarantees excellent light transmission, enhanced durability and consistent performance over time.
The K100 also stands out for its innovative focusing system. It is equipped with a focuser with friction drive with dual controls (patented design), enabling fast, smooth and precise adjustment by moving the primary mirror. A focus distance indicator is integrated, clearly indicating optimum positions for distances of 8 meters, 14 meters and infinity. This feature makes focusing intuitive and particularly effective, even for novice users.
The telescope comes with two eyepieces (10 mm and 20 mm) offering magnifications of 50x and 100x, as well as a 90° bend for optimum viewing comfort. The 5×24 optical finder makes spotting celestial objects easy and pleasant.
A universal smartphone adapter is included, making it easy to capture images of your observations. Compatible with smartphones from 54 to 90 mm wide, it transforms this telescope into a versatile tool for amateur astrophotography.
Compact and lightweight, with a length of just 363 mm and a weight of around 1.68 kg (including accessories), the K100 is ideal for nomadic observations. It features a 45 mm dovetail-type mounting bar with 1/4″-20 thread, making it compatible with many photo tripods and mounts.
This telescope is an excellent choice for enthusiasts who want a high-performance instrument that's easy to carry and use, while benefiting from modern technical innovations.
