Getting to Know Reflecting and Refracting Telescopes
Reflecting Telescopes are exceptional instruments for looking at physical objects in the night sky and the fundamental part of any telescope is the objective. The objective lens is what permits the light into the telescope enabling you to see the projected images from the heavenly objects you are observing. Telescopes with larger objective lenses allow more light in and this means a fresher image for the observing astronomer.
The two fundamental designs of telescopes are reflecting telescopes and refracting telescopes. These two types are quite similar in design apart from for the fashion in which they collect light.
The Key Differences in Refracting and Reflecting Telescopes
The objective lens in refracting telescopes is a piece of glass that is situated close to the front end of the telescope. The objective directs the light that it collects and refracts, or deflects, it to send it to the eyepiece, which magnifies the image. Refracting telescope technology is also an important elementin other scientific equipment like binoculars, rifle scopes and spyglasses.
By comparison, reflecting telescopes are unique because the objective is a reflective mirror at the distal end of the telescope instead of a glass lens at the front. The mirror in a reflecting telescope has a dished shape, or a bowl-like shape, which allows it to catch the light in the central of the mirror and send it as one stream of light towards the eyepiece so the image can be seen by the observer.
Why Use a Reflecting Telescope
Reflecting telescopes are the best choice by many astronomers for several reasons. A primary reason is less distortion with a reflecting telescope than with a refracting telescope since the mirror is able to gather and reflect all wavelengths of color consistently. The utilising of the mirrors instead of glass lenses generally makes reflecting telescopes more affordable than refracting telescopes.
When mirrors are used instead of glass lenses, the telescope can be designed much larger to allow for the supports for the mirror to be located on the posterior of the telescope. The larger the mirror that is used, the more light can be reflected and the better and clearer the image will be.
Specific Issues with the Reflecting Telescope
Reflecting telescopes can have their own issues and problems as well. One problem can be the size of reflecting telescopes. As designers use larger and larger mirrors, the telescopes have to grow in size to fit the mirrors inside. While the images are better with the larger reflecting telescopes, they are not what you would call easily portable and it can prove awkward finding a suitable place to keep them when you are not using them.
Another problem is that reflecting telescopes may need to have the mirrors from time to time to keep them working perfectly and to maximize the light that is captured.
Many of the most common and favored telescope brands offer both refracting and reflecting style telescopes for the recreational astronomer.
Virtually all of the better telescopes used in research are reflectors. Reflecting telescopes come in numerous design variations and may utilise complementary optical elements to enhance image quality or place the image in a mechanically advantageous position. Since reflecting telescopes utilise mirrors, the design is sometimes referred to as a catatropic telescope.
