Hopkins Ultraviolet Telescope
The Hopkins Ultraviolet Telescope (HUT) was a space telescope for the ultraviolet spectral range with a mirror diameter of 90 cm, which was used together with other telescopes in the shuttle missions STS-35 (Astro-1, December 2-11, 1990) and STS-67 ( Astro-2, March 2-18, 1995) was used.
HUT was developed by the Johns Hopkins University in Baltimore. The only observation instrument was a spectrograph that covered the wavelength ranges 82.5 to 185 nm and 42 to 92.5 nm with about 0.3 nm resolution. Together with two other ultraviolet telescopes UIT and WUPPE , HUT was mounted on the jointly adjustable observation platform IPS in the cargo bay of the space shuttle. In total, over 300 celestial objects, from planets to active galaxies , were observed.
