A secondary-mirror chopper system has been introduced in a balloon-borne far-infrared 60-cm diameter telescope equipped with He-cooled filters and a composite silicon bolometer with an NEP of 1.3 10 to the -14th W/sq rt H2 for imaging, radiometery and spectroscopy of the Cygnus region at the wavelengths 80, 130 and 310 microns. The modified system was flown on September 26/27, 1990 with a hydrogen balloon at the CNES station at Aire/Adour, France. Observations were performed at a platform height of 39 km during the course of 5 hrs. Measurements on the complexex DR21 and S106 of the Cygnus region as well as on Mars were performed successfully.
