A balloon borne telescope for infrared astronomy
Abstract
A balloon borne telescope with an aperture of 50 cm has been built for infrared astronomical observations. A Nasmyth focus is added to the conventional Cassegrain focus to provide a stable platform for delicate instruments as cryogenically cooled spectrometers. Pointing and tracking accuracies as good as 15 arcsec are achieved in cooperation of a control momentum gyro (C.M.G.) torquer and an offset star tracker.
