Buying a Telescope | Features of a Refracting Telescope

In this basic telescope guide, we will discuss information about refracting telescopes, the interesting facts and the ways to troubleshoot common problems that plague the users of these telescopes.

We all know that refractor telescopes mostly use lens instead of mirrors that are found in many reflecting telescopes. Because of its mechanism, light would be relayed to the opening and then it would pass through layers of lens before it would reach the last lens where the viewer can clearly see whatever they focus on. This is what enables refractive telescopes have more clarity, an advantage over the reflecting telescope that a lot of people prefer. Another interesting fact is that the famed Italian scientist named Galileo used the refractor telescope as a way to discover the stars, the planets and the other findings including the fact that the moon had a crusty texture compared to other planets etc. The largest telescope was created at the Yerkes Observatory in Williams Bay, Wisconsin on 1897 and can still be found there today.

But of course, this telescope has its own set of disadvantages as well. There is one common problem that bothers hobbyists who carry these old models: the discoloration of certain parts when looking at planets is a common issue, a problem that is called Chromatic Aberration; though these kinds of problems can be easily solved with a simple purchase of a couple of filters to improve the image of your telescope. Aside from this problem is the minor problem that involves air bubbles being inside the lens of the telescope, the only solution that can be done about this is to simply buy a new Reflecting telescope.

Refracting telescopes have gone a long way since the time of Galileo, they have not only changed the way we see the stars and the night sky, but how we see our selves in our little planet as well. It revolutionized astronomy and much of the field would not exist without it. Today, because of the simple technology that these machines brought society hundreds of years ago, improvements in ways that we would never have expected such is the example of the reflecting telescope has improved focal range, created our huge database of stars and enabled us to remotely control our view from the a computer hook up system that processes the data at lightning fast speeds and extreme accuracy.
