William Sadler Franks
William Sadler Franks (26 April 1851 in Newark, Nottinghamshire – 19 June 1935 in East Grinstead) was a British astronomer. Franks was elected to the Royal Astronomical Society on 9 January 1880. From 1890 to 1894 he directed the British Astronomical Association’s Star Colour Section. He published a catalogue of the colours of 3890 stars. Franks was employed between 1892 and 1904 by the wealthy amateur astronomer Isaac Roberts as an assistant to support the photographic observations of star clusters and nebulae at Roberts's private observatory at Crowborough in Sussex. In 1910 he was hired by F. J. Hanbury (of the Allan and Hanbury firm) to work as an observer at Hanbury's private Brockhurst Observatory at East Grinstead in Sussex. He continued his studies of the colours of stars there, and also made micrometer (device), micrometer measurements of double stars. In 1923 he won the Jackson-Gwilt Medal of the Royal Astronomical Society. One of the other observers who used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Patrick Moore
Sir Patrick Alfred Caldwell-Moore (; 4 March 1923 – 9 December 2012) was an English amateur astronomer who attained prominence in that field as a writer, researcher, radio commentator and television presenter. Moore was president of the British Astronomical Association; co-founder and president of the Society for Popular Astronomy; author of over seventy books on astronomy; and presenter of the world's longest-running television series with the same original presenter, BBC's ''The Sky at Night'' (from 1957). He became known as a specialist in Moon observation and for creating the Caldwell catalogue. Idiosyncrasies such as his rapid diction and monocle made him a popular and instantly recognisable figure on British television. Outside his field of astronomy, Moore was known for his role on the video game television show '' GamesMaster''. Moore was also a self-taught xylophonist and pianist, as well as an accomplished composer. He was an amateur cricketer, golfer and chess pla ...

Society For The History Of Astronomy
The Society for the History of Astronomy is an organisation based in the United Kingdom that promotes research into the history of astronomy. It publishes a research journal called ''The Antiquarian Astronomer'' and a regular ''Bulletin''. The society The Society for the History of Astronomy was founded in 2002 to promote the study of the history of astronomy by hosting talks by members and publishing new research into the field. One main objective was to encourage research into past astronomers who have previously been neglected within the history of science. Some of its members are professional historians of science but most are amateur historians. The honorary president is Dr Allan Chapman of Wadham College, Oxford. The honorary vice-presidents are Emily Winterburn (who was chair at the time of foundation) and Prof. Mike Edmunds. Previous vice-presidents have included Sir Patrick Moore, Sir Arnold Wolfendale, FRS, and Dr Michael Hoskin. The society hosts several one-day ...

Jackson-Gwilt Medal
The Jackson-Gwilt Medal is an award that has been issued by the Royal Astronomical Society (RAS) since 1897. The original criteria were for the invention, improvement, or development of astronomical instrumentation or techniques; for achievement in observational astronomy; or for achievement in research into the history of astronomy. From 2017 onwards, the history of astronomy category has been removed and transferred to a new award, the Agnes Mary Clerke Medal. The frequency of the medal has varied over time. Initially it was irregular, with gaps of between three and five years between awards. From 1968 onwards it was awarded regularly every three years; from 2004 every two years; and since 2008 it has been awarded every year. The award is named after Hannah Jackson ''née'' Gwilt. She was a niece of Joseph Gwilt (an architect and Fellow of the RAS) and daughter of George Gwilt (another Fellow); Hannah donated the original funds for the medal. It is the second oldest award is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Double Star
In observational astronomy, a double star or visual double is a pair of stars that appear close to each other as viewed from Earth, especially with the aid of optical telescopes. This occurs because the pair either forms a binary star (i.e. a binary system of stars in mutual orbit, gravitationally bound to each other) or is an ''optical double'', a chance line-of-sight alignment of two stars at different distances from the observer. Binary stars are important to stellar astronomers as knowledge of their motions allows direct calculation of stellar mass and other stellar parameters. The only (possible) case of "binary star" whose two components are separately visible to the naked eye is the case of Mizar and Alcor (though actually a multiple-star system), but it is not known for sure whether Mizar and Alcor are gravitationally bound. Since the beginning of the 1780s, both professional and amateur double star observers have telescopically measured the distances and angles between d ...

Micrometer (device)
A micrometer, sometimes known as a micrometer screw gauge, is a device incorporating a calibrated screw widely used for accurate measurement of components in mechanical engineering and machining as well as most mechanical trades, along with other metrological instruments such as dial, vernier, and digital calipers. Micrometers are usually, but not always, in the form of calipers (opposing ends joined by a frame). The spindle is a very accurately machined screw and the object to be measured is placed between the spindle and the anvil. The spindle is moved by turning the ratchet knob or thimble until the object to be measured is lightly touched by both the spindle and the anvil. Micrometers are also used in telescopes or microscopes to measure the apparent diameter of celestial bodies or microscopic objects. The micrometer used with a telescope was invented about 1638 by William Gascoigne, an English astronomer. History The word ''micrometer'' is a neoclassical coinage ...
