Using CCD’s in Introductory-Level College Astronomy Laboratories
Published online by Cambridge University Press: 12 April 2016
Extract
Our university recently purchased a liquid-nitrogen-cooled CCD camera system (from Photometrics Ltd., Tucson, Arizona) which has been installed on our campus’ 40-cm multiple access (Cassegrain/Newtonian) telescope. Images are reduced online at the observatory using Photometrics’ microcomputer-based analysis software package, which includes operations for standard data acquisition and initial stages of data reduction — including corrections for bias, dark current, and flat fielding. Images are displayed on a 256-level-gray-scale black and white monitor. Additional post-processing can be done either on the CCD system’s computer at the observatory or on IBM-AT/PC’s located both at the observatory and in the laboratory.
