For those who have a passion for astronomy and must choose a telescope, there are some characteristics to evaluate to avoid scams.

The telescope it is very practical to offer essential vision and precision when watching the stars and the firmament. There are quite a few in the market, but before purchasing a specific model, it is important to carefully examine a few criteria to get the most out of the astronomical experience.

However, it is essential to specify that they exist three macro categories within which you can choose and they have very different characteristics.

THE refracting telescopes they are the “traditional” ones that are seen most frequently. Then there are the reflecting telescopes which on the market are differentiated into two types: Newtonian and Debosian. And finally we find i catadioptric telescopesthe two recognized types of which are the Schmidt-Cassegrain and the Maksutov-Cassegrain.

Choosing the telescope: here are the characteristics to observe

The choice of a telescope will be based on different criteria. Although there are many elements to take into account, there are essentially three functions to remember when choosing a device, namely: magnification of the object that you want to observe, the brightness range and obtaining one excellent resolution.

Having said that, exactly as happens in all other purchases, the first thing to look at when buying a telescope is the price. Generally, models that are under 100 euros are suitable for children and not for adults, as they are considered “toys”. For this reason it is necessary to consider an expense above i 100 euros.

It is important to observe theeye of the telescope, because that is where the images come from and it must be of good quality to have the maximum visual experience. In order for the eyepiece to be replaced it is important to know the maximum focal lengththis way the device will offer a better resolution.

Another crucial element of the telescope is the seeker, basically a small telescope that is generally found next to the eyepiece; there are various models and you are spoiled for choice. Also note the mount, i.e. the system that allows the movement of the telescope, which can be altazimuth or equatorial. In any case, you can always rely on the hands of an expert who sells them and who can help you with your choice.
