1. reflecting telescopenoun

   A telescope which produces a magnified image by reflecting light through a series of mirrors housed in a tube, using a large curved mirror to gather the light and one or more additional mirrors to transmit the light to an eyepiece.

1. Reflecting telescope

   A reflecting telescope (also called a reflector) is a telescope that uses a single or a combination of curved mirrors that reflect light and form an image. The reflecting telescope was invented in the 17th century by Isaac Newton as an alternative to the refracting telescope which, at that time, was a design that suffered from severe chromatic aberration. Although reflecting telescopes produce other types of optical aberrations, it is a design that allows for very large diameter objectives. Almost all of the major telescopes used in astronomy research are reflectors. Many variant forms are in use and some employ extra optical elements to improve image quality or place the image in a mechanically advantageous position. Since reflecting telescopes use mirrors, the design is sometimes referred to as a catoptric telescope. From the time of Newton to the 1800s, the mirror itself was made of metal – usually speculum metal. This type included Newton's first designs and even the largest telescopes of the 19th century, the Leviathan of Parsonstown with a 1.8 meter wide metal mirror. In the 19th century a new method using a block of glass coated with very thin layer of silver began to become more popular by the turn of the century. Common telescopes which led to the Crossley and Harvard reflecting telescopes, which helped establish a better reputation for reflecting telescopes as the metal mirror designs were noted for their drawbacks. Chiefly the metal mirrors only reflected about 2⁄3 of the light and the metal would tarnish. After multiple polishings and tarnishings, the mirror could lose its precise figuring needed. Reflecting telescopes became extraordinarily popular for astronomy and many famous telescopes, such as the Hubble Space Telescope, and popular amateur models use this design. In addition, the reflection telescope principle was applied to other electromagnetic wavelengths, and for example, X-ray telescopes also use the reflection principle to make image-forming optics.

1. reflecting telescope

   A reflecting telescope, also known as a reflector, is a type of optical telescope that uses a single or combination of curved mirrors to reflect light and form an image. These mirrors are used to gather more light and focus it into a beam that can be observed and analyzed, thus allowing a clear and detailed view of celestial objects. The primary advantages of a reflecting telescope include the ability to view objects in deep space such as nebulae and galaxies, as they can produce high-resolution and high-magnification images without suffering from chromatic aberration, which is common in refracting telescopes. The two main types of reflecting telescopes are the Newtonian reflector and the Cassegrain reflector.
