Loomis Observatory
Loomis Observatory (also known as the Elias Loomis Observatory) is the second oldest observatory in the United States, located in Hudson, Ohio. Construction was completed in 1838. It is on the campus of Western Reserve Academy, a college preparatory school. When the observatory was constructed the school was Western Reserve College, which later repaired to Cleveland and is now known as Case Western Reserve University. The Loomis Observatory is the oldest observatory in the United States still sitting in its original location. The oldest American observatory, the Hopkins Observatory at Williams College, also completed in 1838, has been relocated twice in its history. Under the influence and design of Professor Elias Loomis, who purchased the necessary instruments in England after studying in Europe, the observatory was built by architect Simeon Porter. The original Troughton & Simms equatorial telescope and Robert Molyneux-built astronomical clock remain in the observatory datin ...

Observatory
An observatory is a location used for observing terrestrial, marine, or celestial events. Astronomy, climatology/meteorology, geophysical, oceanography and volcanology are examples of disciplines for which observatories have been constructed. Historically, observatories were as simple as containing an astronomical sextant (for measuring the distance between stars) or Stonehenge (which has some alignments on astronomical phenomena). Astronomical observatories Astronomical observatories are mainly divided into four categories: space-based, airborne, ground-based, and underground-based. Ground-based observatories Ground-based observatories, located on the surface of Earth, are used to make observations in the radio and visible light portions of the electromagnetic spectrum. Most optical telescopes are housed within a dome or similar structure, to protect the delicate instruments from the elements. Telescope domes have a slit or other opening in the roof that can be opened ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hopkins Observatory
Hopkins Observatory is an astronomical observatory owned and operated by Williams College in Williamstown, Massachusetts (USA). Constructed in 1838 by Albert Hopkins, the college claims that it is the oldest observatory in the United States. The observatory dates to 1834 when Prof. Albert Hopkins traveled to England to obtain astronomical equipment. His students constructed the observatory 1836-1838 in the center of the quad. It was moved once in 1908 and again to its present location in 1961, where it now serves as a planetarium. Today's building still contains the original transit, regulator with mercury-compensated pendulum, and rule. The museum's second director, Truman Henry Safford, was a calculating prodigy. In 1852 the firm of Alvan Clark (Cambridge, Massachusetts) built a 7" refracting telescope, which was restored for the observatory's sesquicentennial. In 1963 the planetarium projector was installed and named in memory of Willis Milham, professor of astronomy 1901-19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Williams College
Williams College is a private liberal arts college in Williamstown, Massachusetts. It was established as a men's college in 1793 with funds from the estate of Ephraim Williams, a colonist from the Province of Massachusetts Bay who was killed in the French and Indian War in 1755. It is the second-oldest institution of higher education in the Commonwealth of Massachusetts after Harvard College. Although the bequest from the estate of Ephraim Williams intended to establish a "free school", the exact meaning of which is ambiguous, the college quickly outgrew its initial ambitions. It positioned itself as a "Western counterpart" to Yale and Harvard. It became officially coeducational in the 1960s. Williams's main campus is located in Williamstown, in the Berkshires in rural northwestern Massachusetts, and contains more than 100 academic, athletic, and residential buildings. There are 360 voting faculty members, with a student-to-faculty ratio of 7:1. , the school has an en ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elias Loomis
Elias Loomis (August 7, 1811 – August 15, 1889) was an American mathematician. He served as a professor of mathematics and natural philosophy at Western Reserve College (now Case Western Reserve University), the University of the City of New York and Yale University. During his tenure at Western Reserve College in 1838, he established the Loomis Observatory, currently the second oldest observatory in the United States.

Troughton & Simms
Troughton & Simms was a British scientific instrument firm. It was formed when Edward Troughton in his old age took on William Simms as a partner in 1826. It became a limited company in 1915 and in 1922 it merged with T. Cooke & Sons to form Cooke, Troughton & Simms. The firm had its origins in the instrument-making business begun in 1764 by John Troughton (1716-1788). This business was successively passed down first to nephews, John Troughton (1739-1807) and then to Edward Troughton (1756-1835). In 1826 Edward Troughton took on William Simms as partner. Origins In 1756, John Troughton Senior from Corney, Cumberland, set up business in London, having completed his apprenticeship with London instrument maker Thomas Heath. In 1769, his nephew John Troughton Junior, after completing his apprenticeship with his uncle, set up in business for himself. He took over the business of Benjamin Cole in 1782, a maker of orreries at a shop in Fleet Street called "At the Sign of The Orr ...

Equatorial Telescope
An equatorial mount is a mount for instruments that compensates for Earth's rotation by having one rotational axis, the polar axis, parallel to the Earth's axis of rotation. This type of mount is used for astronomical telescopes and cameras. The advantage of an equatorial mount lies in its ability to allow the instrument attached to it to stay fixed on any celestial object with diurnal motion by driving one axis at a constant speed. Such an arrangement is called a sidereal or clock drive. Equatorial mounts achieve this by aligning their rotational axis with the Earth, a process known as polar alignment. Astronomical telescope mounts In astronomical telescope mounts, the equatorial axis (the ''right ascension'') is paired with a second perpendicular axis of motion (known as the ''declination''). The equatorial axis of the mount is often equipped with a motorized "'' clock drive''", that rotates that axis one revolution every 23 hours and 56 minutes in exact sync with the ...

Astronomical Clock
An astronomical clock, horologium, or orloj is a clock with special mechanisms and dials to display astronomical information, such as the relative positions of the Sun, Moon, zodiacal constellations, and sometimes major planets. Definition The term is loosely used to refer to any clock that shows, in addition to the time of day, astronomical information. This could include the location of the Sun and Moon in the sky, the age and Lunar phases, the position of the Sun on the ecliptic and the current zodiac sign, the sidereal time, and other astronomical data such as the Moon's nodes (for indicating eclipses) or a rotating star map. The term should not be confused with ''astronomical regulator'', a high precision but otherwise ordinary pendulum clock used in observatories. Astronomical clocks usually represent the Solar System using the geocentric model. The center of the dial is often marked with a disc or sphere representing the Earth, located at the center of the Solar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
