Scientific paper

Astronomical data acquisition and processing techniques are presented for accurate photometry at a level of 0.0001 of the background night-sky level. The application of CCDs in astronomical spectroscopy and faint object photometric imaging is discussed. Emphasis is given to data acquisition and digital image processing techniques to remove systematic errors from processed CCD images to levels of less than one photoelectron. It is suggested that the low-light astronomy is limited more by telescope size than by CCD detectors, optics, or atmosphere. Also, future developments such as the large area CCD mosaic cameras are considered.
