The equipment used varies from webcams and basic security cameras to specialized video astronomy cameras. Recent growing interest in the video 'near-live' aspect of astronomy has brought about websites devoted purely to the practice [ 6 ] and forums for users of the equipment [ 7 ] [ 8 ] [ 9 ]
Astrophotography had an early role in sky surveys and star classification but over time it has used ever more sophisticated image sensors and other equipment and techniques designed for specific fields.

Classical Dobsonian mount parts are typically made from plywood and other cheap materials which are glued, screwed, or even nailed together. In contrast to other telescope mount types, no precision-machined mechanical parts are required. For smooth sliding motions, small Teflon (PTFE) blocks are used for the seven supports. Their surface sizes ...
The barn door tracker was created by George Haig. His plans were first published in Sky & Telescope magazine in April 1975. Modified versions of the tracker were published in the magazine's February 1988 and June 2007 editions.
LightBuckets went through an ownership transition in 2011, [citation needed] resulting in a turn-over in what instruments and sites were available. Before then, LightBuckets instruments included Ritchey-Chrétiens by RC Optical Systems including a 0.61 m (24”) f/8 [4] designated LB-0001 and a 0.37 m (14.5") designated LB-0003 both located at the company's observatory in Rodeo, New Mexico.
Clock drive mechanism in the pier of the German equatorial mount for the 8-inch refracting telescope at Aldershot Observatory.. In astronomy, a clock drive (also known as a sidereal drive or field rotator) is a motor-controlled mechanism used to move an equatorial mounted telescope along one axis to keep the aim in exact sync with the apparent motion of the fixed stars on the celestial sphere.
Photometry is also used in the observation of variable stars, [4] by various techniques such as, differential photometry that simultaneously measures the brightness of a target object and nearby stars in the starfield [5] or relative photometry by comparing the brightness of the target object to stars with known fixed magnitudes.
