The Gregorian Telescope is an interesting design of reflector and it was the first practical design for a telescope that used a mirror. It is still used in modern times but only in very limited circumstances.
Telescopes are of two main types – reflectors and refractors. The fundamental difference between both types is the kind of glasses used for light collection. Refractors use lenses while reflectors use mirrors. Going back to school physics, it is obvious that light from distant bodies, like celestial objects, comes at us as a parallel beam. Due to this parallel nature of the light rays, reflector telescopes use parabolic mirrors.
This article takes a look at the two main types of telescopes and explains the benefits of each. It will help you purchase a telescope that is right for your needs, budget, and wants.
Lenses and mirrors are the elements used to collect and view focused light in telescopes. Mirrors are the medium for focusing in reflector telescopes, while lenses are the medium in refractors. Each type has its own distinct advantages and disadvantages. Refractor type telescopes use lenses. These lenses bend the light when it enters the telescope from the distant object being viewed through it. Because of this refraction it is possible to closely view a distant object.
This article won’t give you the complete steps to making your own telescope but it will help you help you figure out what kind of telescope making would be right for you and give you some tips on how to make one. Buying a telescope can sometimes seem a pretty complex and involved process. There are so many aspects to consider: do you want a refracting or reflecting? What sort of magnification? Coated optics or multi-coated? Focal length specs? If you're like most, you just want a middle-of-the-road quality telescope with a...

One must keep in mind the factors that affect the performance of a telescope. It helps in deciding which one to buy.
Are you interested in astronomy? Wouldn't it be great, to really see, what all those shinning points of light are, in the night sky? Well, you can with a telescope, but how to buy a telescope? What do you need to get started in astronomy, and wouldn't it be great to have it all in an easy telescope buying guide, such as this article?
So you've been bitten by the astronomy bug and want to get started with your very own telescope, but you're confused by the vast number of possible purchases?

There are several different types of telescopes. Each has there merits, and it is a good idea to know the difference when looking to buy telescopes. In this article, you will soon discover the main differences in the different types of telescopes, and find out which is the best to buy to get the most from astronomy.
Binoculars and telescopes are basic tools we can use to see images or objects beyond the range of our naked eyes. A good quality of telescope is essential for the best results.
Binoculars and telescopes are used for scientific studies of the universe. It is also used in navigation purposes for...
