Refracting telescopes are the type of telescope we think about, when we use the word - telescope. There are many benefits to buying a refracting telescope. As you read this article, you will discover more about these benefits, and will be able to make a decision on whether to buy refracting or go for reflecting telescopes.
Refracting telescopes operate with lenses. This is the Galileo telescope, and works with light entering an objective lens, traveling through the telescopes tube, and meeting your eye through the optical lenses.
There is something to note about refracting telescopes, and that is that there is a limit with how big a telescope you can buy. Over 150mm objective lens sizes, the price becomes much more expensive than a reflecting telescope.
So, if you want to go for a larger sized telescope, then you may find price verses performance is better with reflecting telescopes. However, there are some benefits of refracting telescopes, which make them much better than reflecting telescopes.
A refracting telescope is all enclosed. And here is where many benefits can be found, over reflecting telescopes. Being closed to the elements, you will find that refractors are much more reliable and maintenance free.
With reflectors, you have to have some maintenance work, over time. As the telescope is open to the elements, it will have need to get work done, on such things as the mirror. The biggest part of maintenance will be with re-coating the mirror.
The design of refractor telescopes is simple in design. This makes it a great telescope to own, as simplicity usually results in reliability.
You will also find that the optics allow an unobstructed path. Light enters through lenses, which have a very minimal loss of light, and provides maximum definition.
Refractor telescopes also are great for beginners to astronomy. Pointing a refractor telescope to our Moon, is easy, and maneuvering the telescope is also easy, due to it's simplicity in design.
Refractors are great for not only viewing the Moon, but also seeing the planets, and even viewing binary stars. For deep space viewing reflector telescopes seem to produce better views, especially considering that over 150mm objective lens sizes in a refractor, a reflector is cheaper, and can produce better results.
Overall, a refractor is great for beginners to backyard astronomy. If the telescope is for children, a refractor can be easier to work with. If you want a telescope which will allow you to start your journey in astronomy, then refracting telescopes can be the best way to go. |
