Tele_Scope_History

Reflector and catadioptric telescopes, optical systems that involve both the reflecting and refracting of light in order to reduce interference and inconsistency, are other types of telescopes that you might have previously have been interested in. The light doesn’t change direction as many times as in a reflector or catadioptric telescopes which improves the final image. Our telescope will not brighten the sky background, reduce contrast, or smear images like other telescopes do, because of the previously stated reasons. Our telescopes transmit 90% or more of the light that enters the objective lens, other telescopes only transmit 35-80% of the light. Also, the smaller versions we sell are much lighter and, just like the one advertised in this brochure, are much more economical than other versions priced $5000-. The first refractor telescope invented was a low magnifying telescope. Marketed as a “spy glass”, many consider this was invented by Hans Lippershey, though many other opticians at the time marketed a similar product though very different superficially. Some people believe that Galileo Galilei invented this product, though in fact he only corrected errs of the design through trial and error. He discovered that by using a convex objective lens and a concave eyepiece the image can be focused better, and see more widely. He was the scientist to use it to investigate science. This still led to the problem in which chromatic aberrations, where the wavelengths of different colors would not line up properly on the same plane of view, and color smearing, especially at the edges, occurred. Later, Chester Moore Hall, a British lawyer and inventor, produced the first lenses that prevented spherical and chromatic aberration in 1729 or 1733. He joined two lenses with different dispersion factors, after polishing the surfaces, and as a result, the different colors’ wavelengths will line up and could now be focused on the same plane of vision. Before, Chester Moore Hall, most lenses were hard to make pure enough to focus well. These and a few other innovations led to our modernized telescope.
