Abstract

We have introduced secondary-mirror chopping in our balloon-borne far-infrared 60 cm telescope equipped with He-cooled filters and a composite silicon bolometer with an NEP of 1.3-10^-14 W/Hz^1/2 for imaging, radiometry and spectroscopy of the Cygnus region at the wavelengths 80 μm, 125 μm and 330 μm. We also report on the flight scheduled for Sept. 1990.
