What is the refractive telescope?

The refractive telescope is the one and uses a glass lens to collect light instead of mirrors used in binoculars on the reflector. This lens, also known as the goal, is probably the most important part of the telescope, as its quality determines the quality of the overall enlargement and the resulting visible image. Most people who have a telescope stored in the attic find that it is a refractive telescope. This advantage of size is facilitated by storage and transport than a much larger reflector. As a result, they are popular to sell in department stores and the like.

The refractory telescope works by bending, ie refractive, light. The target of curved glass is located at one end of the telescope. From the point of view of the object, the light passes to the finish and is bent into the telescope tube. The light is finally reflected up on Mirror at the other end of the tube. The mirror shines the image into the eyepiece.

There are certain characteristics of the refractor telescope that make them more attractive than reflectors for those who are new to look at the star. The optics is less likely to move than the mirrors on the reflector, which is an incidence that causes incorrect alignment and blurring of objects. Reflectors must be "collimated" or aligned, with almost every use and sometimes during temperatures. Refractors do not require any calibration by the user at all. The reflecting telescope is open at one end, which means that the goal can be dirty and must be regularly cleaned, a process that can be dangerous for expensive mirrors if not done correctly. The refractor delsope has a closed tube, which means that dirt and dust cannot accumulate on the inside and therefore does not require internal cleaning.

refractors have disadvantages, especially for those who have more advanced knowledge of astronomy. Are exposed to a number of light anomalies, the most problematic of which is chromatic aberration, which is distortionthat causes a rainbow of light around the displayed objects. The refractive telescope has difficulty accepting certain types of light, especially ultraviolet light that is unable to go through the goal. The larger the telescope, the clearer these problems become. As a result, the refractive telescope is an impractical use for serious research. In general, the refractors are best suited for planetary and lunar monitoring by amateur astronomers.
