For those who love taking knowing more about space and the night sky, telescopes are very important tools to have. Telescopes are great universe portals and have greatly enabled many of the space travellers to have a lot of enjoyments and good times in the space. According to many people especially the beginners in astronomy, getting the best telescopes is a bit challenging to them due to lack of concrete knowledge about the best telescopes. There are some key buying guides that every person in need of a new telescope for his or her space travel should consider so as to make the best choice when buying a telescope. Some major buying guides that can enable you easily find the best telescope for your travel are discussed below.
To get the best telescope, you have to be aware of the various categories of telescopes that you are likely to come across when in need of one. The first type of a telescope is a refractor telescope. Refractor telescopes are greatly preferred by a large number of astronauts because of the quality of images they provide. Refractor telescopes are more rugged than the other types of telescopes something that comes as a result of proper alignment of the various lenses. The reflector telescopes are also very good options that you can have when buying a telescope. One thing that differentiates these types of telescopes from the others is that they collect and focus light by the help of a mirror. The reflector telescopes have fair prices something that makes them very affordable to a large number of prices. Another reason why reflector telescopes are highly preferred is because of their large sizes which make them give very correct image reading other than the mirror reading.
The last types of telescopes are the compound telescopes which are also known as the catadioptric telescopes. The compound telescopes are different from the refractors and the reflectors in the sense that they have both mirrors and the lenses to collect and focus the images.
Different telescopes have different sized lenses and mirrors which are as a result of the difference in their diameters and hence the reason why one is greatly recommended to consider the diameter of the objective lenses and the mirrors. Though telescopes with larger diameters cost more, they are likely to separate objects that are very close to each other than the telescopes with small lenses and mirror diameters. Many people prefer the telescopes with bigger lenses diameters because they work better than those with small diameters. It is very important to ensure that you consider the general magnification of the lenses on the telescopes to enable you get the best telescope. Telescopes whose lenses have a lot of magnification on the images affect the quality of the images and thus not considered to be the best for astronauts. You should also join an astronomy club to teach you about the usage of the telescopes before buying one.
