| Abstract: | A sensitive spectrograph for rocket observations of celestial objects in the 910–1250Å band is described. The instrument incorporates a variety of new technologies that allow unprecedented sensitivity in this difficult, but scientifically rewarding, band. It includes a diamond-turned Wolter-Schwarzschild Type II telescope, a conventional Rowland Circle spectrograph, and resistive anode/micro-channel plate detectors. It has been launched twice from Woomera, Australia where it performed the only observations of SN1987a in its bandpass and discovered a new feature in the diffuse ultraviolet background. |
