The Astronomy telescopes are used by the astronomer to look into the skies. Literally, they blow up or magnify the image of something that is too far away to see in detail.Low-powered telescopes are simply not up to the task of making the target object big enough to the user’s eyes that it appears like the observer is right next in front of the object.

The first astronomy telescopes used the technique of refraction or focusing light at a specific point. However, such a technique produces a halo that shows the color spectrum, which can be annoying to the eyes. This is due to the glass breaking up light into the seven colors.

To address this, Sir Isaac Newton came up with the technique of reflection in which a mirror and lens operate together to display the same image. Essentially, reflector astronomy telescopes are refractors that have a second mirror to reflect the image back to the viewer. [ad#250x250-sq]

As time passed, people improvised on the reflector and refractor techniques and came up with the compound telescope, a hybrid of the two magnifying techniques. One advantage of the compound astronomy telescopes is increased effective focal length and portability. Most compound telescopes can just be folded and packed into a case.

Through the years, scientists have improved on the designs and techniques of astronomy telescopes to come up with unconventional yet equally powerful scopes that they use in their research. These unconventional telescopes deviate from the fundamental mirror-and-lens approach to magnify heavenly bodies.

For example, the Arecibo Observatory does not use lenses in its telescopes. Instead, it makes use of radio waves. The telescope gathers radio waves through a parabolic dish that has holes in it. Other examples of an unconventional astronomy Telescopes include the Chandra X-Ray Observatory and the Spitzer Space Telescope. The former uses X-rays in their telescopes while the latter sees heavenly bodies by using infrared radiation.

Astronomy’s history would never be complete without the astronomy telescopes. The astronomy telescopes have played a very important role in the foundation of this branch of science, and that degree of importance remains until today.
