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 ]
Colour images in typical cameras are made by combining data from red, green and blue pixels. [7] In order to produce a colour image using a monochrome sensor, three monochrome images must be produced and combined to produce a colour image. The three monochrome images are mapped to the respective red, green and blue channels.
Digital camera images may also need further processing to reduce the image noise from long exposures, including subtracting a “dark frame” and a processing called image stacking or "Shift-and-add". Commercial, freeware and free software packages are available specifically for astronomical photographic image manipulation. [17]
Talk about the demise of analog photography has flown around for years, but a small group of film camera enthusiasts have kept the trend alive and well — and one of those people is Barcelona ...
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.

One of the Baker–Nunn cameras used by the Smithsonian satellite-tracking program A Baker-Nunn satellite tracking camera in use. The Baker–Nunn design, by Baker and Joseph Nunn, replaces the Baker-Schmidt camera's corrector plate with a small triplet corrector lens closer to the focus of the camera. It used a 55 mm wide film derived from the ...
Afocal photography works with any system that can produce a virtual image of parallel light, for example telescopes and microscopes. Afocal photographic setups work because the imaging device's eyepiece produces collimated light and with the camera's lens focused at infinity, creating an afocal system with no net convergence or divergence in the light path between the two devices.
