VAIANA Astronomia - Sestante di Hadley (Ramsden) Jesse Ramsden, Londra, 1787 ottone, mogano raggio = 33,5 cm stato: buono Sebbene il sestante di Hadley, o sestante di riflessione non sia uno stromento, che possa avere un grand'uso in uno Osservatorio; tuttavia essendosimi presentata l'occasione di averne uno del Ramsden non volli trascurare di farne l'acquisto. Con queste parole Giuseppe Piazzi, nel libro II della Specola Astronomica giustifica l'acquisto di un sestante eseguito dal celebre Jesse Ramsden (1737-1800). Il suo costo fu di 16 sterline e 16 scellini, come si rileva da un documento di pugno dello stesso Piazzi intitolato: Nota degli stromenti provvisti in Londra dal P. Piazzi per l'Osservatorio di Palermo co' loro prezzi. Un'accuratissima descrizione di questo strumento si trova in un opuscolo dello stesso Ramsden, edito a Londra e privo di data. Il sestante era inoltre corredato da un orizzonte artificiale per le altezze che si prendono in terra .. .; questo accessorio, purtroppo andato perduto, era stato eseguito da Jacob Bernard Haas (1735-1828), allievo di Ramsden, ed era costituito ...

Ramsden Observatory Welcome to Ramsden Observatory! Ramsden Observatory is located on Earth's Moon, in the center of Sinus Medii (literally "The Bay of the Center"), at Lunar geographical coordinates degrees North, degrees East. This location is the Moon's sub-terrestrial point ). The Observatory is named for the British mathematician Jesse Ramsden , who showed that Cassegrain's design for a reflecting telescope reduces the spherical aberration introduced by curved lenses and mirrors( Ramsden Observatory is owned and operated by the Intersettlement Geographic Society, the 23rd century descendant of the National Geographic Society that was founded on January 27, 1888, in the city of Washington DC, the capital of the old, pre-CEGA United States of America. Beginning in the late 21st century, the Society used the Observatory to monitor conditions on Earth during the 100 years of chaos commonly referred to as "The Fall." Today, the Ramsden Observatory continues to study the Earth from afar, under the watchful eyes of the Central Earth Government and Administration. The Observatory welcomes visitors with open arms; there is nothing more beautiful in the entire Solar System than the Homeworld hovering directly overhead!

Ramsden, Jesse - English telescope maker of the late 18th and early 19th centuries. His telescopes were in high demand by astronomers of the time. Riccioli, Giovanni Battista (1598-1671) - Italian astronomer who is credited with naming many features of the moon, including naming the craters after famous scientists. He was also the first to observe a double star through a telescope. Rittenhouse, David (1732-1796) - American clock and instrument maker and astronomer who observed the transit of Venus in 1769 from his Pennsylvania farm. He is considered by many to be the father of American astronomy. Roche, Edouard (1820-1883) - demonstrated that an moon is limited in its orbit around a planet. If the moon passes within a certain distance (Roche Limit) it will be torn apart by the gravitational interactions between itself and the planet. Romer, Ole

38. Antique Telescope By Jesse Ramsden 18 th Century Telescope by jesse ramsden. This is a great example of a late18th century telescope by the famous instrument maker jesse ramsden. http://www.hubbletelescope.btinternet.co.uk/ramsden.shtml

Home The Sky this month The Planets The Sun ... Links th Century Telescope by Jesse Ramsden This is a great example of a late 18th century telescope by the famous instrument maker Jesse Ramsden. He was born in Halifax in 1731 and he died in Brighton in 1800. All of his work is of the highest standard, which is evident when using this telescope. The achromatic objective lens is shown above in its brass surround. This unscrews using the knurled ring to allow access to the back of the glass for cleaning. Ramsden employed over 50 men, but he was said to have undertaken the construction of the most delicate instruments himself. The telescope is made of brass and mahogany. These were typical telescope making materials from the 18th century, especially for marine use. The photograph above shows the barrel, and the screws that attach the wood to the brass. At the front there are four screws, and at the opposite end of the barrel there are six screws. Not only is this telescope in superb working order, it also has its original leather case. I believe that it is original as it fits so well and slides in and out very smoothly. The eyepiece end of the telescope is shown in the two photographs above . The protective shutter rotates around a pivot and does not slide along straight tracks. The eyepiece design employed is known as the "Ramsden" as it was developed by Ramsden earlier in his life. A variation of Ramsden style eyepieces, the Kellner, is still used in telescopes today.

Aberration Any errors that result in image degradation. Such errors may be chromatic, spherical, astigmatic, or comatic, and can result from design or execution, or both. In an optical system, the aberration of light refers to the straying away of rays from their appointed courses. These errors, unless corrected, tend to produce a hazy image and give rise to spherical aberration, coma, astigmatism, curvature of field, distortion, and longitudinal and lateral chromatic error.
