All refracting telescopes use the same principles. The combination of an objective lens 1 and some type of eyepiece 2 is used to gather more light than the human eye is able to collect on its own, focus it 5, and present the viewer with a brighter, clearer, and magnified virtual image 6. The objective in a refracting telescope refracts or bends light. This refraction causes parallel light rays to converge at a focal point; while those not parallel converge upon a focal plane. The teles… WebApr 28, 2008 · The credit for being the first modern telescope generally goes to the 9" Dorpat refractor in Estonia. That was the first Fraunhofer as such as far as I know.
