There are many different types of telescopes, and the type you choose depends on where you want to use it. For example, if you want to look at stars and planets, a reflector telescope is best. If you want to view distant galaxies or nebulae, a refractor telescope is more suited for that task.
Reflector Telescopes
Reflector telescopes use a mirror to gather light and reflect it into an eyepiece or other instrument. They are generally the least expensive type of telescope and their design is simple, which makes them easy to use. Reflectors have a limited amount of magnification power compared to refractors or catadioptric telescopes.
Refractor Telescopes
Refractor telescopes have a long tube and use lenses to collect light. Their design allows them to focus more light than reflector telescopes, which means they can be used in low-light conditions including during the day time. An additional benefit is that refractor telescopes tend to be smaller than reflectors with similar magnification capabilities. However, refractors are also more expensive than reflectors because they require more complex lenses that can be costly to manufacture and maintain over time. You can check Celestron Telescopes for more information.
Radio Telescopes: Radio telescopes are used to study the radio spectrum and are usually large in size. They can be used to detect the presence of planets and stars, as well as other objects such as comets and asteroids. Radio telescopes work by reflecting radio waves off of large parabolic dishes. Radio telescopes are used to detect radio waves emitted from space sources like stars and galaxies (see picture above). They pick up these radio waves with antennas built into them

Catadioptric Telescopes
Catadioptric telescopes, also known as compound telescopes are a combination of both refracting and reflecting telescopes. They use mirrors and lenses together to achieve the best possible image quality. Catadioptric telescopes can be very powerful and they are used by professional astronomers. A catadioptric telescope combines both mirrors and lenses in its design to produce a compact, lightweight telescope with good image quality over a wide range of magnifications. The advantage of catadioptric telescopes is that they can be made smaller than other types of telescopes, such as refracting or reflector telescopes. The disadvantages include higher cost and complexity of construction.
Optical Telescope: The optical telescope uses lenses to focus light from distant objects onto an image plane, which can then be viewed from an eyepiece on the side of the telescope tube. The main disadvantage of this type of telescope is that it requires bulky equipment.
Infrared Telescope: An infrared telescope uses infrared light, which cannot be seen by humans but can be detected by special cameras or other devices such as thermometers. Infrared light is invisible because it has longer wavelengths than visible light (between 700 nanometers and 1 millimeter). You can contact us Telescopes UK for more information.
