With a ground version of a wide angle camera, proper images of large scale galactic structures were obtained within the range 2000 to 20,000 A. For SPACELAB applications, a similar instrument can be developed with increased spectral range to 900 A. For this purpose basic analysis was necessary regarding the optics and the detector system. Furthermore, investigations on filters, reflecting surfaces, and spectral shifters as well as on mechanical problems and compatibility with SPACELAB were necessary to establish and select feasible concepts. The increased spectral range turned out to be feasible only by mirror optics. A promising alternative to photographic film is the microchannel plate-detector still under development. Problems remain regarding sensitivity between 900 and 1100 A, but results do not rule out a possible solution.
