Abstract

We show that infrared telescopes can be constructed at low cost using consumer-grade thermal infrared imagers and commercially available germanium lenses. Using these telescopes in the laboratory, introductory astronomy students can image nearby celestial objects to observe properties that are not seen in the visible region, in particular, variations in temperature across the surface.
