CCD imaging camera and CCD based guiding system at the 1 meter UPSO telescope

Abstract

Two CCD imaging camera systems acquired from Photometrics USA have been installed at the Cassegrain focus of 1 meter Uttar Pradesh State Observatory (UPSO) telescope. A 384 x 576 pixels Thomson CCD based camera system has been working since November 1989 and 1024 x 1024 pixels Tektronic CCD chip based camera system has been installed in February 1993. The details of their configuration for image acquisition, display and processing are described. The facilities of image processing available at UPSO are also described. A CCD based star tracker/imaging camera has also been acquired and installed in the eyepiece hole of 20 cm guiding telescope, which is an auxiliary telescope of 1 meter reflector. The working of this instrument as star tracker is described.
