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 ]
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.
Cold camera photography is a technique used by astrophotographers to reduce the electronic noise that accumulates during long exposures with the electronic sensors in DSLRs and dedicated CMOS or CCD astro-cameras. Cooling is usually accomplished with a Peltier thermo-electric cooler.
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.
The STARS real-time star tracking software operates on an image from EBEX 2012, a high-altitude balloon-borne cosmology experiment launched from Antarctica on 2012-12-29. A star tracker is an optical device that measures the positions of stars using photocells or a camera. [1]
Amateur astronomers engage in many imaging techniques including film, DSLR, LRGB, and CCD astrophotography. Because CCD imagers are linear, image processing may be used to subtract away the effects of light pollution, which has increased the popularity of astrophotography in urban areas. Narrowband filters may also be used to minimize light ...
