In addition, due to advancement in technology, there is a third type of scope which is a hybrid of a reflector and a refractor – the Schmidt and or Makustov Cassegrain telescopes. The mirrors on these scopes are exposed to the outside environment, so you need to delicately clean them every so often.The secondary flat mirror blocks light on the way to the primary mirror.There is no chromatic aberration with reflecting scopes, but you need to do collimation or alignment of the base mirror and secondary flat mirror.Once size nears 100mm, when compared to its refractor counterpart, a reflector is more cost-efficient because mirrors are cheaper to make than lenses.It is also portable due to its compact size.Using larger apertures allows more light through, and there will be a better view of very distant galaxies and other celestial bodies.The resulting image viewed from this telescope is brighter and sharper.No color fringing and blurred images because of all wavelengths of light travel at the same speed as it gets reflected.To further understand the significance of this telescope, below are some of its common pros and cons. This telescope is commonly used in a standing position when viewing galaxies and other distant celestial objects. If one wants to view and observe deep-space-objects (DSO’s), then a reflecting telescope is much preferable. Each model has its specific innovation and purpose of using. There are several new models of telescopes available in the market today. When is a Reflector Better over Other Telescopes This mechanism is beneficial in creating sharper and accurate images. Mirrors have the capabilities of reflecting and concentrating light rays to a single focal point. The result of this problem is a blurred image.Ĭonsequently, mirrors were used in replacement of lenses. As light passes through the lens, it breaks into different wavelengths and travels at various speeds. The primary factor of this problem is lens dispersion. To solve this problem, a reflecting telescope was built using mirrors instead of lenses.Ĭhromatic aberration happens when the lenses are unable to focus all light or color to a similar focal plane. However, refractors have some setbacks such as chromatic aberrations or fringing of colors. Refracting telescopes were the first thing made to study celestial bodies in the early centuries of research and development. Aside from that, Leonardo da Vinci also used concave mirrors in studying celestial bodies a century before Newton. The design was a combination of primary concave mirrors and a smaller secondary mirror. Meanwhile, two Catholic priests named Marin Mersenne and Bonaventura Cavalieri were the first one to successfully design a reflecting telescope which got the name Mersenne telescope. Consequently, Nicolo stopped trying and went back to making refracting telescopes. This scientist and an Italian named Jesuit attempted to make a reflecting telescope in 1616 but were not successful. On the other hand, several other people who lived before Newton also made designs and functional models of this reflecting telescope.Ī scientist named Nicolo Zucchi was the first one to build a very simple design telescope. After the successful demonstration, Newton gained membership right away from the said scientific community. Newton tried various metals and polished it to improve reflecting capabilities.Īfter building his first functional model, the Royal Society of London was able to see Newton’s demonstration of it. Sir Isaac Newton was credited as the inventor for the reflecting telescope in 1668. The offer to be be the biggest at most affordable pricing, but why is that? Let’s find out more! To do that, it seems best to start at the beginning? ![]() OK, let us get more detailed to what a reflector telescope is. There are two main benefits from having this telescope: (1) cheaper than refractor telescope and (2) no fringes in the color of the images formed. ![]() A second flat mirror set at 45 degrees located below the aperture redirects the light creating a focal point toward the eyepiece. Utilizing two mirrors a reflector telescope has a concave primary mirror located at the bottom of the telescope. When it comes to viewing celestial bodies in the sky, a reflector telescope can be a good option.
