What Are The Types Of Telescopes?

Introduction

Types of telescopes, as we have already mentioned, are extensive. Therefore, before choosing one, we must consider how dark the sky is where we will make the observations, what we want to observe, if it has to be transport or is going to fix, the level of experience or the budget.

In our Cash Converters stores, you can find a great selection of second-hand telescopes, whether you want to start in the world of stargazing or if you are looking to improve your equipment with a more advanced telescope. In addition to having an exceptional price, they all have a two-year guarantee.

How Does A Telescope Work?

The Function of an astronomical telescope is to collect light and allow distant objects to be seen. The vast majority have a series of curved mirrors responsible for collecting and focusing the light. These mirrors are call “optics”.

And although mirrors are use today, due to their lightness and the ease of making them completely smooth. The first telescopes are made with lenses from transparent and curve glass pieces.

The larger the telescope’s optics, the more capacity it will have to collect light and allow you to see more distant and dim objects.

Types Of Telescopes

Refracting Telescopes

This type of telescope stands out for being one of the easiest to use since it only has two lenses.

Its operation, like its use, is straightforward. One end of the telescope collects the light reflected by the lenses to the other end. From where the enlarge image seen through the eyepiece.

The most significant handicap of refracting telescopes is that they are usually cumbersome and large due to the large lenses and the elongated tube-shaped body. In addition, it makes it difficult to transport, so it is a type of telescope recommend to those amateurs who want it always to have it at a fix point.

Catadioptric Telescopes

Catadioptric are a type of hybrid telescope. That is, it is a combination of the previous two.

The light enters the interior of the tube through a corrective lens, is reflect by a primary mirror. A secondary mirror and is reflect primary mirror before reaching the eyepiece.

It has a primary mirror at one end and a secondary mirror, both curved inwards. The primary mirror is responsible for reflecting light to the secondary mirror and the eyepiece. As a general rule in this type of telescope, this last element is located on one of the sides.

Reflecting Telescopes

Reflecting telescopes are defined as a type of telescope in its catoptric version. Although they have many aspects in common with refracting telescopes, such as the lenses and tube system, they have other characteristics that make them stand out. An example of this is its compact size, making it an excellent option for effortlessly carrying out night observations.

Conclusion

type of telescope is one of the best options to start in astronomy. However, while they are simple to use and design and often very affordable in price. Close attention must pay to their maintenance due to their expose tube and the ease with which they can become misalign.
