![]() You can find an illustrated construction report here. Of course, a telescope made of cardboard cannot compete with a much more expensive massive instrument, but with this kit you have the opportunity to follow in Newton's footsteps and carry out all the assembly steps yourself, and in the end you will be as surprised by the result as Newton himself was by his first reflecting telescope. A telescope which produces a magnified image by reflecting light through a series of mirrors. For observing sunspots, a solar filter attachment with the Baader AstroSolarTM solar filter foil is available as an accessory. NounEdit reflecting telescope (plural reflecting telescopes). They provide 16x and 30x magnification and allow the viewing of lunar craters and, with careful adjustment of the main mirror, also of Jupiter's moons. The eyepieces are equipped with optics made of acrylic glass. The centrepiece is the main mirror, a spherical precision mirror made of ground and polished glass with a diameter of 70 mm and a focal length of 450 mm, which was specially calculated and manufactured for this kit. The performance of the Astro-Didactic reflecting telescope is about the same as Newton's first homemade instruments. Newton's first mirrors, which he ground and polished himself with tools he built for the purpose, had diameters of 25 and 50 mm respectively, a focal length of 300 mm and could magnify about 30 times. However, these problems are not as significant as in refractors, and the reflecting telescopes are always cheaper too. Reflecting telescopes are often linked with Newtonian telescopes, as they’re the most common type of reflecting telescope. The problems are coma or comatic aberration, and they require more maintenance than reflecting telescopes. The light is reflected in a bundle and directed sideways into an eyepiece by a small, slanted flat mirror. The reflecting telescopes suffer from a few problems as well. He simply replaced the converging lens with a converging mirror. 1703-1727) is generally I credited with the invention of the reflecting telescope, having conceived the idea in. Isaac Newton (1643-1727) solved the hitherto existing problems of refracting telescopes in 1668 with the invention of his reflecting telescope. As the name suggests, catadioptric telescopes use both lenses and mirrors. Reflector vs refractor vs catadioptric Telescopes. So they require more maintenance than refractors. ![]() They do need regular collimation and cleaning. A fully functional reflecting telescope with 16x and 30x magnification and Dobsonian mount Reflecting telescopes can suffer from aberrations (other than chromatic) and contrast issues.
