Paper Abstract

Cooled, slow-scan CCD cameras are the systems of choice when there is a requirement for systems to work at the lowest light levels or with the most extreme dynamic range. Systems are available now with as much as 20-bit dynamic range and intelligent read-out (multiple sub- arrays, on chip binning, on board processing power). The principal draw-back in such systems is the relatively slow read-out rate that makes such systems inappropriate for the measurement of fast changing scenes that require real-time response and often makes the setting-up of a slow-scan system especially tedious (alignment and focusing). A new CCD system has been developed by Astromed that allows the best of both worlds. It provides a fast read-out rate for alignment, focusing or set-up, and a selection of slower rates for data taking. Full on-chip binning, and sub-array read-out are allowed with a wide dynamic range, fast analog-to-digital converter. A sophisticated software package allows an extensive range of data taking, reduction, display and analysis facilities.
