Abstract
An I-SIT television system using a 40 mm S-1 image tube fiber-optically coupled to a 40 mm SIT vidicon tube has been used extensively for astronomical observations in the near-infrared. The camera and data acquisition system is briefly described and the digital picture reduction scheme is illustrated with both spectroscopic and direct imaging data. Observations of the red supergiant star Betelgeuse (α Orionis) are presented that reveal the remarkable extent of the gas shell that surrounds the star. A brief interpretation of these data in terms of mass loss is presented. Planetary observations of Jupiter in the methane band (λ 8900 Å) are also discussed.
