A good example is the Schmidt Cassegrain scope. Some of the modern telescopes today are even hybrids of a refractor and reflector telescope. In fact, a simple refractor scope is the best considering those who are starting out with astronomical studies. True, that refractor telescopes have limitations and setbacks, but it does not remove the fact that it is still a viable tool. Why Do We Still Use Refractor Style Scopes Instead of having a tube 150 feet long, the length of the refractor scope was able to shrink to about 8 to 20 inches. Dollond created the first patented achromatic refracting lens in 1733. Luckily, John Dollond, a British optician, found a cure for this issue. Later on, issues about spherical and chromatic aberration sprung up in the community. Galileo’s enhanced refractor became the first viable telescope for astronomical studies. This improved scope made use of a convex lens to make the outcome image in an upright orientation. Meanwhile, the first version of the refractor was further enhanced by Galileo in Venice during 1609. This situation burst out the controversy of who is the legitimate inventor of the said tool. For instance, Jacob Metius has applied for a patent of his refractor telescope at the same time as Hans and Zacharia. This has been considered as the first invention, although some parts of the world have been using refractors at some point in time already. The first invention of a refractor telescope was in the Netherlands in 1608 by Hans Lippershey and Zacharia Jannsen. But the final decision of whether to have one or not rests in your hands.īelow are some more in-depth details regarding refractor telescopes. This telescope has several things to admire and gripe about. The eyepiece magnifies and straightens the light for your eye. Light travels through the objective lens and is slightly bent (refracted) to create a focal point for the eyepiece to receive. The first design being crude, but functional viewed distant objects on the horizon and in space, which led to discovery and understanding of the night sky.Ī refractor telescope is composed of two lenses an objective lens and an eyepiece. In contrast to reflecting telescopes, a refractor telescope or refractors make use of lenses to gather light from objects and direct it towards the eyepiece.
