Abstract

We present the first surface photometries of the Southern Milky Way (; ) at 217 nm and 280 nm. The resolution is . They are based on photographs obtained with the shuttle-borne GAUSS-Camera as part of the German Spacelab Mission D-2. These photometries are the extensions of the earth-bound photometries (Kimeswenger et al. 1993 = Paper VII; Hoffmann et al. 1997 = Paper VIII) to the ultraviolet. The data processing was modified to adapt it to the new data. Both photometries are strongly affected by interstellar extinction especially of local dark clouds. Hence, they provide a comprehensive overview of scattering caused light emission in our Galaxy.
