Thanks to its ingenious optical design, it combines primary and secondary mirrors with a sub-aperture corrector lens, enabling the focal length to be \u201cfolded\u201d into a short, easily transportable tube.<\/p>\n<p>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.<\/p>\n<p>The primary and secondary mirrors are treated with a special <strong>Radiant\u2122 Aluminum Quartz (RAQ\u2122)<\/strong>, offering up to 94 % reflectivity. This technology guarantees excellent light transmission, enhanced durability and consistent performance over time.<\/p>\n<p>The K100 also stands out for its innovative focusing system. It is equipped with a <strong>focuser with friction drive<\/strong> 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.<\/p>\n<p>The telescope comes with two eyepieces (10 mm and 20 mm) offering magnifications of 50x and 100x, as well as a 90\u00b0 bend for optimum viewing comfort. The 5\u00d724 optical finder makes spotting celestial objects easy and pleasant.<\/p>\n<p>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.<\/p>\n<p>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\u2033-20 thread, making it compatible with many photo tripods and mounts.<\/p>\n<p>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.<\/p>\n<h3>Klevtsov-Cassegrain K100 technical specifications<\/h3>\n<table border=\"1\" cellspacing=\"0\" cellpadding=\"8\">\n<tbody>\n<tr>\n<th>Features<\/th>\n<th>Detail<\/th>\n<\/tr>\n<tr>\n<td>Type<\/td>\n<td>Klevtsov-Cassegrain (catadioptric)<\/td>\n<\/tr>\n<tr>\n<td>Diameter<\/td>\n<td>100 mm<\/td>\n<\/tr>\n<tr>\n<td>Focal length<\/td>\n<td>1000 mm (f\/10)<\/td>\n<\/tr>\n<tr>\n<td>Magnifications supplied<\/td>\n<td>50x and 100x<\/td>\n<\/tr>\n<tr>\n<td>Maximum useful magnification<\/td>\n<td>200x<\/td>\n<\/tr>\n<tr>\n<td>Eyepieces included<\/td>\n<td>10 mm and 20 mm (1.25\u2033)<\/td>\n<\/tr>\n<tr>\n<td>Researcher<\/td>\n<td>5\u00d724<\/td>\n<\/tr>\n<tr>\n<td>Angled return<\/td>\n<td>90\u00b0 Star Diagonal (1,25\u2033)<\/td>\n<\/tr>\n<tr>\n<td>Optical treatment<\/td>\n<td>RAQ\u2122 (up to 94 % reflectivity)<\/td>\n<\/tr>\n<tr>\n<td>Focusing<\/td>\n<td>By moving the primary mirror with a friction system<\/td>\n<\/tr>\n<tr>\n<td>Focus indicator<\/td>\n<td>Yes (8 m, 14 m, infinity)<\/td>\n<\/tr>\n<tr>\n<td>Mounting<\/td>\n<td>45 mm dovetail + 1\/4\u2033-20 thread<\/td>\n<\/tr>\n<tr>\n<td>OTA length<\/td>\n<td>363 mm<\/td>\n<\/tr>\n<tr>\n<td>OTA weight<\/td>\n<td>1.68 kg (with accessories)<\/td>\n<\/tr>\n<tr>\n<td>Accessories<\/td>\n<td>Universal smartphone adapter (54-90 mm)<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Visit <strong>K100 Klevtsov-Cassegrain<\/strong> is a compact, innovative telescope offering excellent image quality in a portable format.
