| الوصف: | The Hopkins Ultraviolet Telescope (HUT) is a 90-cm f/2 prime focus telescope and spectrometer with a photon-counting microchannel plate detector designed to obtain moderate resolution (wavelength interval, approximately 4 A) spectrophotometry of faint (visual magnitude, less than approximately 17) objects in the far-ultraviolet spectral region (approximately 900-1700 A). The HUT will be mounted on the Spacelab Instrument Pointing System and will be operated by a Payload Specialist using a field acquisition TV system to assist in locating targets. The initial flight of the HUT, expected in 1984 or 1985, will be devoted primarily to the study of quasars and active galactic nuclei, emphasizing the 900-1200 A spectral region which is inaccessible with other existing or currently planned orbiting instruments. |
