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.
KStars is a freely licensed planetarium program using the KDE Platform. It is available for Linux, BSD, macOS, and Microsoft Windows. A light version of KStars is available for Android devices. It provides an accurate graphical representation of the night sky, from any location on Earth, at any date and time. The display includes up to 100 million stars, 13,000 deep sky objects, constellations from different cultures, all 8 planets, the Sun and Moon, and thousands of comets, asteroids, satellites, and supernovae. It has features to appeal to users of all levels, from informative hypertext articles about astronomy, to robust control of telescopes and CCD cameras, and logging of observations of specific objects.
The Adler Planetarium is a public museum dedicated to the study of astronomy and astrophysics. It was founded in 1930 by Chicago business leader Max Adler. It is located on the northeast tip of Northerly Island at the shore of Lake Michigan in Chicago, Illinois. The Adler was the first planetarium in the United States and is part of Chicago's Museum Campus, which includes the John G. Shedd Aquarium and The Field Museum. The Adler's mission is to inspire exploration and understanding of the universe.
Sky & Telescope (S&T) is a monthly American magazine covering all aspects of amateur astronomy, including the following:
Stardome Observatory is a public astronomical observatory situated in Maungakiekie/One Tree Hill Domain in New Zealand's largest city, Auckland.
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.
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.
The Amateur Astronomers Association of Pittsburgh (AAAP) was founded on June 9, 1929, by Chester B. Roe and Leo J. Scanlon. Since then, it has grown to over 500 members and operates two observatories in the Pittsburgh region: the Nicholas E. Wagman Observatory and the Mingo Creek Park Observatory. The club also sponsors many star parties that are open to members of the public throughout the year.
Rainwater Observatory and Planetarium is an educational astronomical observatory and Planetarium run as an educational ministry of French Camp Academy. It is located near French Camp, Mississippi, United States. It is the largest observatory in Mississippi with 16+ telescopes, with the largest instruments including a 32-inch Dobsonian telescope and 14-inch Celestron catadioptric telescope. Rainwater is currently awaiting delivery of the Sollee Telescope, a 25-inch research-grade telescope. When installed in the two-story observatory building already constructed in the observatory complex, the Sollee Telescope will be suitable for serious astronomical studies, in the last remaining "dark spot" in Mississippi on the U.S. Dark Skies photograph.
The Society for Popular Astronomy (SPA) is a national astronomical society based in the United Kingdom for beginners to amateur astronomy.
ASCOM is an open initiative to provide a standard interface to a range of astronomy equipment including mounts, focusers and imaging devices in a Microsoft Windows environment.
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.
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.
Sky-Map.org is a wiki and interactive sky map that covers more than half a billion celestial objects. Users can view the whole star sky at once and zoom in to view areas in greater detail. WikiSky includes many stars, galaxies, constellations, and planets, but it is still in development. Users can also edit information about different stars by writing articles, adding Internet links, uploading images, or create a special interest group for a specific task. The website, although still available for users to visit, has not shown much activity since 2010.
WorldWide Telescope (WWT) is an open-source set of applications, data and cloud services, originally created by Microsoft Research but now an open source project hosted on GitHub. The .NET Foundation holds the copyright and the project is managed by the American Astronomical Society and has been supported by grants from the Moore Foundation and National Science Foundation. WWT displays astronomical, earth and planetary data allowing visual navigation through the 3-dimensional (3D) Universe. Users are able to navigate the sky by panning and zooming, or explore the 3D universe from the surface of Earth to past the Cosmic microwave background (CMB), viewing both visual imagery and scientific data about that area and the objects in it. Data is curated from hundreds of different data sources, but its open data nature allows users to explore any third party data that conforms to a WWT supported format. With the rich source of multi-spectral all-sky images it is possible to view the sky in many wavelengths of light. The software utilizes Microsoft's Visual Experience Engine technologies to function. WWT can also be used to visualize arbitrary or abstract data sets and time series data.
The Celestron SkyScout was a model of handheld consumer electronic instrument for astronomical orientation and education, similarly to the competitor product mySky by Meade Instruments. The general class of zero-magnification sky-orientation scopes using modern geodesy was made possible by the commercialisation of GPS and other GNSS systems in the early 21st century, and the SkyScout was an early example of such use despite being hampered by technical and price limitations.
Digital Universe Atlas is a free open source software planetarium application, available under the terms of the Illinois Open Source License, and running on Linux, Windows, macOS, AmigaOS 4, and IRIX.
