Photographic plates preceded photographic film as a capture medium in photography, and were still used in some communities up until the late 20th century.
Several important applications of astrophotography, including astronomical spectroscopy and astrometry, continued using plates until digital imaging improved to the point where it could outmatch photographic results.
Mount for instruments that compensates for Earth's rotation by having one rotational axis, the polar axis, parallel to the Earth's axis of rotation.
Also, for astrophotography, the image does not rotate in the focal plane, as occurs with altazimuth mounts when they are guided to track the target's motion, unless a rotating erector prism or other field-derotator is installed.
A Schmidt camera, also referred to as the Schmidt telescope, is a catadioptric astrophotographic telescope designed to provide wide fields of view with limited aberrations.
Hobby where participants enjoy observing or imaging celestial objects in the sky using the unaided eye, binoculars, or telescopes.
One branch of amateur astronomy, amateur astrophotography, involves the taking of photos of the night sky.
Brightest star in the northern constellation of Lyra.
Vega was the first star other than the Sun to have its image and spectrum photographed.
Telescope that gathers and focuses light mainly from the visible part of the electromagnetic spectrum, to create a magnified image for direct visual inspection, to make a photograph, or to collect data through electronic image sensors.
The electronics revolution of the early 21st century led to the development of computer-connected telescopes in the 2010s that allow non-professional skywatchers to observe stars and satellites using relatively low-cost equipment by taking advantage of digital astrophotographic techniques developed by professional astronomers over previous decades.
Art, application, and practice of creating durable images by recording light, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film.
Because of the superior dimensional stability of glass, the use of plates for some scientific applications, such as astrophotography, continued into the 1990s, and in the niche field of laser holography, it has persisted into the 21st century.
Presence of unwanted, inappropriate, or excessive artificial lighting.
Even at apparent clear night skies, there can be a lot of stray light that becomes visible at longer exposure times in astrophotography.
Mechanical structure which supports a telescope.
The telescope's field-of-view rotates at varying speed as the telescope tracks, whilst the telescope body does not, requiring a system to counter-rotate the field of view when used for astrophotography or other types of astronomical imaging.
