Jeremiah Sisson
Jeremiah Sisson (1720-1783) was an English instrument maker who became one of the leaders of his profession in London. Jeremiah Sisson was the son of Jonathan Sisson, also a respected instrument maker, who trained him in the craft. Sisson worked at a time when demand from the Royal Observatory, Greenwich and the Ordnance Survey, and assistance from the Royal Society, had brought London instrument makers to a dominant position in supply of the technically demanding work of making instruments for astronomy, survey and navigation. Sisson's father also employed John Bird, another supplier of instruments to the Royal Observatory. Sisson employed Jesse Ramsden in his workshop, later to become a leading instrument maker in his own right. According to Jean Bernoulli, among the London instrument makers in 1769 Sisson ranked after John Bird but ahead of Ramsden in his skill. Jeremiah Sisson supplied sectors and other astronomical instruments to Nevil Maskelyne, Astronomer Royal at the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Brera Astronomical Observatory
The Brera Observatory ( it, Osservatorio Astronomico di Brera) is an astronomical observatory in the Brera district of Milan, Italy. It was built in the historic Palazzo Brera in 1764 by the Jesuit astronomer Roger Boscovich. Following the suppression of the Jesuits by Clement XIV on 21 July 1773, the palace and the observatory passed to the then rulers of northern Italy, the Austrian Habsburg dynasty. From 1 December 1786, the Austrian Empire adopted “transalpine time”. The astronomers were engaged by Count Giuseppe Di Wilczek, the plenipotentiary governor of Lombardy, to build a meridian line inside Milan Cathedral. It was constructed by Giovanni Angelo Cesaris and Francesco Reggio, with Roger Joseph Boscovich acting as a consultant. Following the independence of Italy in 1861, the observatory has been run by the Italian government. In 1862, the newly installed Italian government improved the observatory's facilities by commissioning a 218mm Merz Equatorial Refracting T ...

Thomas Hornsby
Thomas Hornsby (1733 in Durham – 11 April 1810 in Oxford) was a British astronomer and mathematician. Life Hornsby became a Fellow of Corpus Christi College, Oxford in 1760. He occupied the Savilian Chair of Astronomy at Oxford University from 1763. In the same year, he became Sedleian Professor of Natural Philosophy. Hornsby was especially concerned with the observation of the transit of Venus. In 1761, he observed the transit of Venus from Shirburn Castle, in Oxfordshire, the seat of the Earl of Macclesfield. George Parker, 2nd Earl of Macclesfield (ca. 1695–1764), celebrated as an astronomer, had spent most of his time conducting astronomical observations at Shirburn Castle; here he had built an observatory and a chemical laboratory. Despite the international efforts made to observe the 1761 transit, poor weather conditions hampered observations. In 1766 Hornsby informed the Royal Society that preparations needed to begin for the 1769 transit, his publication in the ...

Christian Mayer (astronomer)
Christian Mayer (20 August 1719 Mederitz – 16 April 1783 in Mannheim) was a Moravian-German Catholic priest, astronomer and teacher. Life He was born in Mederitz, Moravia. He became educated in Greek, Latin, mathematics, philosophy, and theology, although his place of studies is unknown. In his early twenties he decided to become a Jesuit, a path which caused him to leave his home due to the disapproval of his father. He entered the Society of Jesus in Mannheim in 1745. After completing his training he began teaching humanities. By 1752 his reputation was such that he was selected as a professor of mathematics and physics at Heidelberg. By this age, however, he had developed a strong interest in astronomy. He was appointed Court Astronomer at Mannheim, and was tasked with selecting the instruments for the new observatories at Schwetzingen and Mannheim. With these completed, he was able to pursue his astronomical studies, and published numerous works. In 1769 he wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Celestial Pole
The north and south celestial poles are the two points in the sky where Earth's rotation around a fixed axis, axis of rotation, indefinitely extended, intersects the celestial sphere. The north and south celestial poles appear permanently directly overhead to observers at Earth's North Pole and South Pole, respectively. As Earth spins on its axis, the two celestial poles remain fixed in the sky, and all other celestial points appear to rotate around them, completing one circuit per day (strictly, per sidereal time, sidereal day). The celestial poles are also the poles of the celestial equatorial coordinate system, meaning they have declinations of +90 degrees and −90 degrees (for the north and south celestial poles, respectively). Despite their apparently fixed positions, the celestial poles in the long term do not actually remain permanently fixed against the background of the stars. Because of a phenomenon known as the precession of the equinoxes, the poles trace out ci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
