	William Herschel - Wikipedia, the free encyclopedia
		On April 3, 1786, William Herschel moved his family to a new residence on Windsor Road in Slough.
		Herschel discovered that unfilled telescope apertures can be used to obtain high angular resolution something which became the essential basis for interferometric imaging in astronomy (in particular Aperture Masking Interferometry and hypertelescopes).
		Herschel discovered infrared radiation by passing sunlight through a prism and holding a thermometer just beyond the red end of the visible spectrum.

	Telescope - MSN Encarta
		A telescope in which the objective is a convex lens (sometimes consisting of two or three components) is called a refractor; instruments that use a concave mirror as the objective are called reflectors.
		The mirrors for early reflecting telescopes were usually made of speculum-metal, a mixture of copper and tin, until the German chemist Baron Justus von Liebig discovered, in the mid-19th century, a method of depositing a film of silver on a glass surface.
		The twin telescopes, 85 m (280 ft) apart, combine their images using a technique that is the optical analogue of the interferometry that has long been carried out in radio astronomy.

	William Herschel Telescope - Wikipedia, the free encyclopedia
		The William Herschel Telescope or WHT was first conceived in the late 1960s, when the Anglo-Australian Observatory was being designed.
		That year was the 200th anniverary of the discovery of Uranus by William Herschel, and it was decided to name the telescope in his honour.
		Notable discoveries made using the WHT include that of a hot bubble of expanding gas at the centre of the galaxy, suggestive of the presence of a supermassive fl hole; the first observation of the optical counterpart of a gamma-ray burst; and recently, the discovery of a Wolf-Rayet star with the fastest-known stellar wind.

	William Herschel (1738-1822)
		Friedrich Wilhelm Herschel was born in Hannover (Germany) in 1738 as son of Issak Herschel (1707-1767), a musician in the regimental band of the Foot-Guards, and Anna Ilse (b.
		William Herschel died on August 25, 1822 in Slough, England, and was buried in the church of Upton on September 7.
		William Herschel was honored lately by the astronomical community by naming Moon crater Herschel (5.7S, 2.1W, 40 km diameter, in 1935), together with his son John by naming Mars crater Herschel (14.9S, 230.3W, 304 km diameter, in 1973), and a crater on Saturn's moon Mimas (2.9N, 109.5W, in 1982).

	William Herschel (Site not responding. Last check: 2007-10-31)
		William Herschel was born in 1738 in Hanover, Germany.
		Herschel embraced this idea, which had became known as the “island universe theory” and set out to determine the shape of the Milky Way, by “gauging” the number of stars in a given region.
		William had noticed in his survey of the skies that the density of stars varied depending upon what region he was looking at, at the time.

	Herschel Club - Friedrich Wilhelm Herschel
		Friedrich Wilhelm Herschel, better known as Sir William Herschel, was born in Hanover, Germany on November 15, 1738.
		The instruments Herschel had lacked clock drives to keep them trained on the moving sky, so the method he used was to direct his telescope to a point on the meridian and watch what crossed the field of view.
		Herschel's son John took his father's instrument to South Africa where he was able to survey the southern skies.

	BookRags: William Herschel, Sir Biography
		Herschel was given the Copley Medal of the Royal Society and elected a fellow.
		Herschel moved to Windsor, near the King's residence, and in due course was given the patronage for which he had long hoped--a salary for himself and his sister, upkeep for the telescope, and later a very large sum for a 40-foot telescope, the largest ever made before the mid-19th century.
		Herschel reasoned that if one member of a double-star system was much brighter than the other this must be the result of such a coincidence, the brighter star of the pair being much the closer of the two.

	"Explore The Universe" - Featured Artifacts - Herschel's 20-Foot Telescope
		Herschel had a talent for telescope making that matched his passion for studying the heavens.
		The telescope's eyepiece was mounted at the top of the tube, so Herschel observed from a platform that could be raised or lowered as needed.
		Like other early telescope mirrors, it was made of metal (mostly copper and tin) and tarnished quickly, so it had to be repolished often.

	William Herschel's catalog
		William Herschel Museum: William Herschel discovered Uranus in 1781 from a house in Bath, England, which is now a museum.
		William Herschel got interested in systematically looking for, and observing, "nebulae" and star clusters when he was presented a copy of the Messier Catalog in December, 1781.
		William's 1788 marriage, 1792 birth of son John, as well as other discoveries and interests took even more time from the nebula project, so that finally Caroline and William needed full 14 years for the final catalog of 500 objects, leaving "un-swept" significant areas of the sky, in particular around the North Celestial Pole.

		The Herschel Space Observatory is a space-based telescope that will study the Universe by the light of the far-infrared and submillimeter portions of the spectrum.
		Herschel's namesake will give scientists their most complete look so far at the large portion of the Universe that radiates in far-infrared and submillimeter wavelengths.
		Earthbound telescopes are largely unable to observe this portion of the spectrum because most of this light is absorbed by moisture in the atmosphere before it can reach the ground.

	William Herschel - MSN Encarta
		Originally named Friedrich Wilhelm Herschel, he was born in Hannover, Germany.
		He erected a telescope at Slough with a 48-in (1.22-m) mirror and a focal length of 40 ft (12.2 m).
		Herschel was the first to propose that these nebulas were composed of stars.

		This involves removing the mirror cell from the telescope, lowering the mirror to the ground floor, washing off the old surface with caustic soda and resurfacing in a large vacuum tank.
		The effective focal length of the telescope for the Cassegrain and Nasmyth foci is 46.2 m (f/11).

	Chapter 17: Pluto
		Scientists used the fact that even the Spitzer telescope was unable to detect the heat of the extremely distant, cold object to determine it must be less than 1,700 kilometers (about 1,000 miles) in diameter, which is smaller than Pluto.
		In August 2002, a team from Williams College, the University of Hawaii, and MIT, in an expedition arranged by Elliot, Tholen, and Pasachoff to the University of Hawaii's telescope in Mauna Kea, successfully observed the occultation of a faint star by Pluto.
		We were to be deployed to the sides of the large telescopes, perhaps 200 km north or south, to increase the chance that somebody would see the event.

		The Near Earth Asteroid 2002 NY40 was observed with the William Herschel Telescope on La Palma, Canary Islands, on the night of August 17 to 18, 2002.
		This resolution is close to the theoretical limit of the telescope, and sets an upper limit to the size of the asteroid: only 400 metres across at the time of the observations.

	Weasner's Just for Fun!
		God help Herschel's assistant who would be perched in isolation in the small wooden assistant's hut below the telescope; this poor soul was required to turn hand wheels, pull ropes and manually push levers to maintain the telescope as it tracked through the long hours of morning.
		As can be seen, Herschel would stand directly IN FRONT of the telescope opening to observe in the long scaffolding seen at right and merely peer down at the large 40" mirror made of heavy metal, not glass.
		Herschel's telescope was close to a "wonder of the world" in the late 1700's as discovery-upon-discovery was made with this huge instrument.
