There are 3 main types of telescopes and each one performs differently and may be used for dissimilar purposes. If you are mental about buying a telescope to look at stars and deep space then you should know that this might not be inherent if you live in a built up area with light pollution. If it is just the moon and the planets you want to look at then you should now that refractors are better than reflectors for this. If you are prepared to trip with your telescope then you should know which types are fragile and which ones give you the best doing from a smaller scope.
The three types of telescopes that exist for capturing light so that it may be magnified for viewing are Catadioptric, Newtonian Reflector and Refractor.
Telescope
Refractor Telescope
The traditional long-tube looking telescope. The Refractor uses lenses to bend light and this causes the rays to meet at a point on the other end of the telescope. They are magnified by the eyepiece for viewing. There is a large lens on the front of the Refractor, which is the objective lens.
Pros
Requires itsybitsy to no maintenance Excellent for planetary viewing
Cons
Color deviation in achromatic designs Not recommended for deep sky observation
Reflector Telescope
The Newtonian Reflector uses a traditional mirror that is concave. This mirror sends light to a flat mirror which reflects the light out a side occasion and to the eyepiece where it is magnified and focused.
Pros
Best for deep space consideration - Great for looking at remote galaxies Delivers very bright images
Cons
Requires quarterly alignment Requires more complex cleaning of mirrors than other types of the same design
Catadioptric Telescope
The last of the three types of telescopes and currently the most favorite on the market. This type uses a series of lenses and mirrors that fold the light path and send it through to the traditional mirror through a small hole. This allows the light to be magnified and focused for viewing. There are two types of Catadioptric telescopes - Schmidt-Cassegrain and Maksutov-Cassegrain. The Maksutov type has a concave and convex correcting lens where the light enters. The light hits the traditional mirror, is sent back to the secondary mirror and finally sent to the occasion in the back of the telescope.Pros
Portable and easy to use Versatile - good for deep space and planetary observation About the best for focusing Excellent optics
Cons
It does not look like a telescope to many people It is more precious than other Newtonians with the same size occasion for light
Once you know what you want to look at and which of the types of telescope you should select you need to think hard about how much you are prepared to carry around, telescopes can be bulky and your tripod and mount are important bits of added kit. Size determined, you are now ready to see just how much gap ,break you can get for your money. Don't concern yourself with magnification, it is not nearly as leading as is touted and higher magnifications will cause images to be blurry because of air turbulence. The doing of a telescope depends on how much light convention capability it has, the more light it can obtain the better you will see, and this is aperture. As a general rule of thumb, once you know which of the types of telescopes is best for you, get the biggest gap ,break you can afford for your money.
