The Amateur Astronomer was a four-page bulletin published between 1929 and 1935 by the Amateur Astronomers Association of New York. C. S. Brainin was the first editor; a section called "Meteor Notes" was edited by Virginia Geiger starting in 1933. [1]
In 1935, The Amateur Astronomer merged into The Sky published by the Hayden Planetarium. [2] In 1941, The Sky merged with The Telescope to become Sky & Telescope , [3] which has remained in print since then.
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.
Lupus is a constellation of the mid-Southern Sky. Its name is Latin for wolf. Lupus was one of the 48 constellations listed by the 2nd-century astronomer Ptolemy, and it remains one of the 88 modern constellations but was long an asterism associated with the just westerly, larger constellation Centaurus.
Amateur telescope making is the activity of building telescopes as a hobby, as opposed to being a paid professional. Amateur telescope makers build their instruments for personal enjoyment of a technical challenge, as a way to obtain an inexpensive or personally customized telescope, or as a research tool in the field of astronomy. Amateur telescope makers are usually a sub-group in the field of amateur astronomy.
Vulpecula is a faint constellation in the northern sky. Its name is Latin for "little fox", although it is commonly known simply as the fox. It was identified in the seventeenth century, and is located in the middle of the Summer Triangle.
Palomar Observatory is an astronomical research observatory in San Diego County, California, United States, in the Palomar Mountain Range. It is owned and operated by the California Institute of Technology (Caltech). Research time at the observatory is granted to Caltech and its research partners, which include the Jet Propulsion Laboratory (JPL), Yale University, and the National Optical Observatories of China.
Since its founding in 1911, the American Association of Variable Star Observers (AAVSO) has coordinated, collected, evaluated, analyzed, published, and archived variable star observations made largely by amateur astronomers and makes the records available to professional astronomers, researchers, and educators. These records establish light curves depicting the variation in brightness of a star over time.
Eridanus is a constellation in the southern celestial hemisphere. It is represented as a river. It was one of the 48 constellations listed by the 2nd century astronomer Ptolemy, and it remains one of the 88 modern constellations. It is the sixth largest of the modern constellations. The same name was later taken as a Latin name for the real Po River and also for the name of a minor river in Athens.
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.
The Fick Observatory was an astronomical observatory owned and operated by Iowa State University. Located southwest of Boone, Iowa it was named after Davenport, Iowa amateur astronomer Erwin W. Fick. The observatory closed in 2015.
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.
Martz Observatory is a public, not-for-profit organization devoted to the amateur astronomer. The emphasis of the association is observational astronomy, well-rooted in public education and enjoyment of the starry skies. It was founded by, and eventually named after, Marshal Martz, an amateur astronomer from Jamestown, NY who built the first large telescope ever used at the observatory.
The International Year of Astronomy (IYA2009) was a year-long celebration of astronomy that took place in 2009 to coincide with the 400th anniversary of the first recorded astronomical observations with a telescope by Galileo Galilei and the publication of Johannes Kepler's Astronomia nova in the 17th century. The Year was declared by the 62nd General Assembly of the United Nations. A global scheme, laid out by the International Astronomical Union (IAU), was also endorsed by UNESCO, the UN body responsible for educational, scientific, and cultural matters.
The Sky was a magazine for amateur astronomers published between 1935 and 1941. It was the successor to a monthly bulletin called The Amateur Astronomer, which was published by the Amateur Astronomers Association (AAA) of New York City, and a precursor to Sky & Telescope before merging with The Telescope.
The Mills Observatory in Dundee, Scotland, is the first purpose-built public astronomical observatory in the UK. Built in 1935, the observatory is classically styled in sandstone and has a distinctive 7 m dome, which houses a Victorian refracting telescope, a small planetarium, and display areas. The dome is one of two made from papier-mâché to survive in the UK, the other being at the Godlee Observatory.
The Bortle 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. John E. Bortle created the scale and published it in the February 2001 edition of Sky & Telescope magazine to help amateur astronomers evaluate the darkness of an observing site, and secondarily, to compare the darkness of observing sites. The scale ranges from Class 1, the darkest skies available on Earth, through Class 9, inner-city skies. It gives several criteria for each level beyond naked-eye limiting magnitude (NELM). The accuracy and utility of the scale have been questioned in recent research. The table below summarizes Bortle's descriptions of the classes. Some classes can have very drastic differences from the one next to it, e.g, Bortle 4 to 5.
The Confederation of Indian Amateur Astronomers (CIAA) is a national level organisation of amateur astronomers in India that convenes a national meeting of members every year, and coordinates the activities of amateur astronomers throughout the country. It was established in 1993 and registered in 1994, following an Inter-University Centre for Astronomy and Astrophysics meeting in 1991.
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.
Amateur Telescope Making (ATM) is a series of three books edited by Albert G. Ingalls between 1926 and 1953 while he was an associate editor at Scientific American. The books cover various aspects of telescope construction and observational technique, sometimes at quite an advanced level, but always in a way that is accessible to the intelligent amateur. The caliber of the contributions is uniformly high and the books have remained in constant use by both amateurs and professionals.
Robert Edward Cox was an American optical engineer and a popularizer of amateur telescope making. He conducted the popular "Gleanings for ATMs" column in Sky and Telescope magazine for 21 years.
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.
