Astroimaging Video, Webcam and CCD Imaging Electronic astronomy is now becoming more affordable. Astronomical CCD cameras are getting better and cheaper. A very cheap way of experimenting with the technology is to use black and white board cameras the are normally intended for use in security systems. An even better way is to use webcam's or video conferencing cameras. These are very cheap and have the added advantage of producing colour digital images that can be further processed in the computer. Webcam Astronomy CCD Imaging Video Astronomy Piggyback Photography Using a tripod mounted camera with a standard 50mm lens, exposures of about 30 or 40 seconds duration are possible before the Earth's rotation becomes apparent. The celestial sphere will be dragged across the film plane causing stars to appear as short arcs centred on the pole position (currently near Polaris). Longer focal length lenses worsen the problem. Exposures have to be made shorter to prevent star trails from becoming visible. Attaching a camera to an equatorial mounting allows exposure times to be increased, since the camera can track the celestial sphere as the Earth rotates and cancel out star trails. As well as normal telephoto lenses, telescopes can also be used for photography. Both require precise star tracking since motors and gears are not normally made to the necessary accuracy. A separate guide telescope can be used to monitor a suitable star during the exposure. This is the technique that I have used for comet photography.
