We have constructed a liquid nitrogen cooled telescope that was flown in an Aerobee 150 rocket. The telescope allows measurement of absolute ir signal strengths from astronomical objects in the wavelength range out to about 7.5 micro. In contrast to ground-based telescopes, it can observe diffuse as...
