![]() They use mirrors in a specific arrangement to focus the radiation onto a focal plane. X-ray telescopes are used to detect the long wavelength X-rays and things that lie in this spectrum. These devices are also used for detection of microwaves and in special programmes to search for life in space. These signals are then converted into images mostly of astronomical objects. Modern radio telescopes have numerous receivers that allow multiple signals to be received simultaneously. They capture the signals and sample them at different frequencies according to the requirements. Contrary to optical devices, this device does not provide any magnification. Radio telescopes are round dish antennas that collect radio waves. The most common use is in astronomy but these are also used in devices like binoculars and cameras. These types are usually simple in construction so they are regarded as the best cheap telescopes for astrophotography. Catadioptric Telescope: In this telescope, both lenses and mirrors are used to make an image of a distant object with clarity and conciseness.Reflecting Telescope: In this type, mirrors are placed in specific directions to produce an image.It uses lenses to produce the picture onto a center point. Refracting telescope: This was the earliest form of the instrument and it is still very popular today. ![]() There are 3 types of optical telescopes present: They use lenses made of glass or mirrors to pinpoint the light at a specific point. Some optical devices can be used in infrared and ultraviolet range as well because both of these spectrum’s are close to light in electromagnetic radiation. Optical telescopes work with light to make objects more visible. Let’s look at the main types of telescopes and their main uses below. It is interesting to note that the word “telescope” was given by a Giovanni Demisiani who was a Greek mathematician. The Italian astronomer, Galileo produced his own version of the telescope which was aimed at observing space objects. The first traces of a telescope were laid in Netherlands in 1608 when a patent was introduced for the concept of a refractive lens telescope. What is a Telescope?Ī telescope is a device that allows us to see far objects in a magnified state by making use of lenses and related technologies. They are known as telescopes and in this review, we shall discover all about the best telescopes for sale in 2020. Fortunately, science has become so advanced that there are devices which help us to watch distant objects clearly. However, most of them are millions of miles away from us and we are not able to see them with the naked eye. If you are a nature lover or excited about space, you may want to observe the various elements present in this Universe.
