Amateur astronomy is a hobby where participants enjoy observing or imaging celestial objects in the sky using the unaided eye, binoculars, or telescopes. Even though scientific research may not be their primary goal, some amateur astronomers make contributions in doing citizen science, such as by monitoring variable stars, double stars, sunspots, or occultations of stars by the Moon or asteroids, or by discovering transient astronomical events, such as comets, galactic novae or supernovae in other galaxies.
John Lowry Dobson was an American amateur astronomer and is best known for the Dobsonian telescope, a portable, low-cost Newtonian reflector telescope. He was also known for his efforts to promote awareness of astronomy through public lectures including his performances of "sidewalk astronomy". Dobson was also the co-founder of the amateur astronomical group, the San Francisco Sidewalk Astronomers.
Sky & Telescope (S&T) is a monthly magazine covering all aspects of amateur and professional astronomy, including what to see in the sky tonight and new findings in astronomy. Other topics we cover:
The American Association of Variable Star Observers (AAVSO) is an international nonprofit organization. Founded in 1911, the organization focuses on coordinating, analyzing, publishing, and archiving variable star observations made largely by amateur astronomers. The AAVSO creates records that establish light curves depicting the variation in brightness of a star over time. The AAVSO makes these records available to professional astronomers, researchers, and educators.
The Astronomical Society of the Pacific (ASP) is an American scientific and educational organization, founded in San Francisco on February 7, 1889, immediately following the solar eclipse of January 1, 1889. Its name derives from its origins on the Pacific Coast, but today it has members all over the country and the world. It has the legal status of a nonprofit organization.
A deep-sky object (DSO) is any astronomical object that is not an individual star or Solar System object. The classification is used for the most part by amateur astronomers to denote visually observed faint naked eye and telescopic objects such as star clusters, nebulae and galaxies. This distinction is practical and technical, implying a variety of instruments and techniques appropriate to observation, and does not distinguish the nature of the object itself.
Terence Dickinson was a Canadian amateur astronomer and astrophotographer who lived near Yarker, Ontario, Canada. He was the author of 14 astronomy books for both adults and children. He was the founder and former editor of SkyNews magazine. Dickinson had been an astronomy commentator for Discovery Channel Canada and taught at St. Lawrence College. He made appearances at such places as the Ontario Science Centre. In 1994, the International Astronomical Union committee on Minor Planet Nomenclature named asteroid 5272 Dickinson in honour of his "ability to explain the universe in everyday language".
Albert Graham Ingalls was an American scientific editor and amateur astronomer. Through his columns in Scientific American, including "The Amateur Scientist", and his three-volume series Amateur Telescope Making, Ingalls exerted a great influence on amateur astronomy and amateur telescope making in the United States.
Astronomy is a monthly American magazine about astronomy. Targeting amateur astronomers, it contains columns on sky viewing, reader-submitted astrophotographs, and articles on astronomy and astrophysics for general readers.
Sidewalk astronomy or street corner astronomy refers to the activity of setting up a telescope in an urban place on a for-profit or non-profit basis as entertainment and/or for public education.
Visible-light astronomy encompasses a wide variety of astronomical observation via telescopes that are sensitive in the range of visible light. Visible-light astronomy is part of optical astronomy, and differs from astronomies based on invisible types of light in the electromagnetic radiation spectrum, such as radio waves, infrared waves, ultraviolet waves, X-ray waves and gamma-ray waves. Visible light ranges from 380 to 750 nanometers in wavelength.
The Caldwell catalogue is an astronomical catalogue of 109 star clusters, nebulae, and galaxies for observation by amateur astronomers. The list was compiled by Patrick Moore as a complement to the Messier catalogue.
Astronomy Now is a monthly British magazine on astronomy and space. According to the Royal Astronomical Society, Astronomy Now is the "principal amateur astronomy magazine in Britain" with a reputed circulation of 24,000.
The Bortle dark-sky scale is a nine-level numeric scale that measures the night sky's brightness of a particular location. It quantifies the astronomical observability of celestial objects and the interference caused by light pollution. Amateur astronomer John E. Bortle created the scale and published it in the February 2001 edition of Sky & Telescope magazine to help skywatchers evaluate the darkness of an observing site, and secondarily, to compare the darkness of observing sites.
David John Eicher is an American editor, writer, and popularizer of astronomy and space. He has been editor-in-chief of Astronomy magazine since 2002. He is author, coauthor, or editor of 23 books on science and American history and is known for having founded a magazine on astronomical observing, Deep Sky Monthly, when he was a 15-year-old high school student.
Paul Boltwood was a Canadian amateur astronomer. He was engaged in developing hardware and software for deep sky imaging and in research of brightness variations in active galactic nuclei. He was also acknowledged for his studies of near-nucleus activity in Comet Hyakutake.
Nicholas Szymanek, better known as Nik Szymanek, is a British amateur astronomer and prolific astrophotographer, based in Essex, England.
Puckett Observatory is a private astronomical observatory located in the state of Georgia. It is owned and operated by Tim Puckett. Its primary observation goals are the study of comets and the discovery of supernovae. To facilitate the latter goal it sponsors the Puckett Observatory World Supernova Search whose astronomers have discovered 369 supernovae.
The Telescope was a magazine for amateur astronomers published between 1931 and 1941. The magazine was first published as a quarterly under the editorship of Harlan Stetson, director of the Perkins Observatory in Ohio. It featured popular articles about contemporary research. In 1934 Stetson moved to Cambridge, Massachusetts and brought the magazine with him. Publishing duties were assumed jointly by the Harvard College Observatory and the Bond Astronomical Club, under the editorship of Donald H. Menzel. The Telescope became a bimonthly publication at this time.
Steve Mandel is an amateur astronomer and astrophotographer. He owns a small observatory, called Hidden Valley Observatory, in Soquel, California. He has been acknowledged especially for his wide-field photographs of the Milky Way nebulae and for public outreach, for which he has received Amateur Achievement Award of the Astronomical Society of the Pacific. Besides this he has also captured and published wildlife images of endangered animals. He works as an American communications coach for professional executives, and is the founder of the Mandel Communications Inc., which aims to teach effective communication and public speaking.
