Telescopes are used by both amateur and professional astronomers to observe celestial bodies such as planets, stars and galaxies. There are many kinds of telescopes available in the market. If you have decided to buy one, it is important to know the different types of telescopes so that you can get the best product at a reasonable price.
Reflector
A reflector telescope uses mirrors to gather light from the object being viewed, reflect it toward the primary mirror, then reflect it back through a lens in the eyepiece. The advantage of this design is that they are relatively inexpensive and easy to build. The disadvantage is that they tend to be heavier than refractors due to the extra weight of the mirrors. They also require more maintenance since dust can gather on the surface of your mirror over time which will affect your viewing experience.
Refractor
A refractor telescope uses lenses instead of mirrors to gather light from an object being viewed. Lenses are thinner than mirrors, so they are lighter and easier to use at high magnifications while still maintaining a high quality image. However, because they don’t have as much power as reflectors (they aren’t able to gather as much light), they’re not as good at showing faint objects like planets or nebulae but are great for viewing brighter objects like stars and galaxies due to their ability to gather lots of light from these sources.
The most common type of telescope is a refracting telescope, which uses lenses to collect light and magnify objects. Refracting telescopes are great for viewing planets, comets and deep space objects like nebulae and galaxies because they can gather more light than other types of telescopes making them easier to see faint objects. Reflecting telescopes use mirrors instead of lenses and are commonly used by amateur astronomers because they are less expensive, easier to use and require less maintenance than refractors. Another advantage is that they don’t have chromatic aberration like refractors do where different wavelengths of light focus at different points creating blurry images.
Catadioptric
These telescopes combine both lenses and mirrors in one unit for maximum clarity and brightness when viewing objects far away from Earth or close-up views without distortion from atmospheric interference. Catadioptric telescopes are often referred to as Schmidt-Cassegrain telescopes (SCTs) because they were first developed by Bernhard Schmidt in the 1930s at the University of Hamburg in Germany (Cassegrain was one of his colleagues).
