Telescopes are very commonly used instruments that help in viewing far away objects with ease. The distant objects appear magnified and closer. There are different models available in the market these days and hence it might be a challenge to choose the right telescope.
There are two types of telescopes and they are the reflector, and the refractor telescopes. Before purchasing one, you have to decide on the type of telescope you need. The reflector telescope is the best to view the objects in the sky as it does not give any kind of distorted images. This is the best type of telescope that can be used by the amateurs. These telescopes are available in different price and the costlier ones help you to reach the maximum extent of the universe.
The refractor telescope consists of two lenses, the convex and the concave. This type of telescope produces some distortion because of the bending of colours into the lens. If you are buying a costlier instrument then this distortion would not take place. When you travel for long distances then choose a telescope that is small and light weight so that they can be carried in the backpacks.
One of the other factors that you should consider is the brand name of the telescope. The brand name of the instrument is certainly important as it contributes to its quality. You can blindly trust the ones that have been in the market for a very long time.
As there are different types of telescopes available in the market, the Dobsonian telescope is the most common among beginners. These instruments are cost effective and at the same time produce good quality. As a basic model, they do not have any high specifications and any kind of complicated computerized gadgets on them. However their optical lenses are brilliant. After you gain the right amount of experience, you can certainly shift to other telescopes that have advanced features and quite expensive. Some of the expensive telescopes are apochromatic refracting telescope and Schmidt Cassegrain .
The main feature of the telescopes that has to be considered while purchasing is the aperture. The diameter of the aperture is most important factor to be taken into consideration while purchasing the telescope. Generally the telescopes purchased by the beginners have an aperture with either 6 inches or 8 inches or 10 inches. If you can afford it, purchase either an 8 or 10 inch version. The task of viewing dim objects becomes easier when the diameter of the mirror is large. The prices vary depending on the size of the aperture and a 6 inch aperture might cause roughly about 230 USD.
Also, check if the telescope that you are ready to purchase comes along with the eyepieces, usually they do. The eyepieces are useful when it comes to magnification. Try purchasing the ones with eyepieces else you might have to buy them separately. These are some of the factors that you can consider before purchasing one. You can choose to buy them in various stores or through online shopping.
