Apollo Observatory
Apollo Observatory is an astronomical observatory owned by Boonshoft Museum of Discovery and operated by the Miami Valley Astronomical Society at Boonshoft Museum of Discovery. The observatory is located at Boonshoft Museum of Discovery in Dayton, Ohio, United States. History and Details The observatory is named after Project Apollo and was dedicated in 1969. Because of its location in the vicinity of a major Air Force research and development arm at Wright-Patterson Air Force Base (WPAFB), it has benefited from an infusion of top-notch technical talent. With funds raised by both the Museum and the Miami Valley Astronomical Society (MVAS), a design by Richard Buchroeder was selected and built by members of the Society, many of whom worked in optics and engineering disciplines for the Air Force. Due to the selected design, the optical train was complex and turned out to be problematic to maintain. It was therefore later modified to a simpler Dall-Kirkham Cassegrainian des ...

Telescope
A telescope is a device used to observe distant objects by their emission, absorption, or reflection of electromagnetic radiation. Originally meaning only an optical instrument using lenses, curved mirrors, or a combination of both to observe distant objects, the word ''telescope'' now refers to a wide range of instruments capable of detecting different regions of the electromagnetic spectrum, and in some cases other types of detectors. The first known practical telescopes were refracting telescopes with glass lenses and were invented in the Netherlands at the beginning of the 17th century. They were used for both terrestrial applications and astronomy. The reflecting telescope, which uses mirrors to collect and focus light, was invented within a few decades of the first refracting telescope. In the 20th century, many new types of telescopes were invented, including radio telescopes in the 1930s and infrared telescopes in the 1960s. Etymology The word ''telescope'' was coin ...

Mirror Grinding
A mirror or looking glass is an object that reflects an image. Light that bounces off a mirror will show an image of whatever is in front of it, when focused through the lens of the eye or a camera. Mirrors reverse the direction of the image in an equal yet opposite angle from which the light shines upon it. This allows the viewer to see themselves or objects behind them, or even objects that are at an angle from them but out of their field of view, such as around a corner. Natural mirrors have existed since prehistoric times, such as the surface of water, but people have been manufacturing mirrors out of a variety of materials for thousands of years, like stone, metals, and glass. In modern mirrors, metals like silver or aluminium are often used due to their high reflectivity, applied as a thin coating on glass because of its naturally smooth and very hard surface. A mirror is a wave reflector. Light consists of waves, and when light waves reflect from the flat surf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
