Abstract

A 2.3 m infrared telescope at Jelm Mountain, Wyoming, is described in terms of its design and operating characteristics. The basic principles of IR astronomy are reviewed, together with an overview of the type of objects which lend themselves to IR observation, e.g., young hot stars, gaseous nebulae, stellar envelopes, etc. Attention is given to mechanisms whereby background and source radiation may be differentiated. It is noted that the primary mirror can concentrate more than 60% of the 5000 A light from a distant point source into a 0.1 sec diameter circle. The telescope is steered by twin PDP 11/34 computers (one is a backup), and equipped with television graphics and floppy-disk memory systems.
