NASA NTRS1972

Far-infrared observations of celestial objects by balloon-borne telescope.

The instrument described is an f/5 Newtonian telescope with a parabolic pyrex primary mirror. The telescope tube is 1.5 m long. A 61 cm baffle is included to provide shielding from off-axis objects such as the earth, the moon, and the sun. An outline of the regions covered by sky surveys in June 1970 and in April 1971 is presented. Approximately 750 square degrees of the sky have been covered, including 100 degrees along the galactic plane.

NASA NTRS1971

100-micron survey of the galactic plane.

A survey of a portion of the galactic plane has been carried out at a wavelength of 100 micron with a beamwidth of 12 min. The survey covers 750 square degrees of the sky including most of the galactic plane between 335 and 88 deg galactic longitude and a number of other selected areas of interest. Seventy-two sources have been detected, 60 of which are identified with continuum radio sources, bright nebulae, dark nebulae, and infrared stars.
