Abstract Large area multi-layer proportional chambers filled with Xenon have been developed for the study of cosmic X-ray sources in 20 – 100 keV range. The X-ray telescope consists of two such detectors, each having an effective area of 1200 cm2 and equipped with a 5° x 5° FWHM collimator, mounted on a servo-controlled orientation platform for making pointed mode observations. Superior energy resolution of the Xenon detectors, being 10 % FWHM at 22 keV, makes them well suited for detection of cyclotron emission lines in the spectra of X-ray pulsars. The X-ray light curves and energy spectrum of the 4.8 hour binary Cyg X-3, observed in a balloon flight in March 1986 is described.
