During the Astro Spacelab missions, the Ultraviolet Imaging Telescope (UIT) obtained spatially-resolved far- (lambda lambda ~ 1500 Angstroms) and mid-UV (lambda lambda ~ 2500 Angstroms) imagery of ~ 50 nearby galaxies. The sample spans the Hubble sequence including ellipticals, disk systems, and irregular galaxies. These images have a resolution of ~ 3arcsec , a limiting surface brightness of mu_ {1500} ~ 25 mags arcsec(-2) , and cover the full spatial extent of each system, many of which have angular diameters exceeding 5(') . We are constructing datasets which combine the UV imagery obtained by UIT with associated optical (UBVRI,Hα ) and near-IR (JHK) images of comparable depth and spatial resolution obtained at ground-based telescopes. Our primary goal is to provide a morphological Atlas of Galaxies extending from the far-ultraviolet (lambda lambda ~ 1500 Angstroms) to near-infrared (lambda lambda ~ 2.2mu ) wavelengths. The Astro-1/UIT Atlas contains registered and flux-calibrated images at FUV, NUV, R and Hα bandpasses and surface brightness profiles for galaxies which display extended structure, as well as integrated magnitudes (or upper limits) for the entire sample. The Astro-2/UIT Atlas contains FUV, U, R, and Hα images for ~ 40 systems, complemented by NIR images for the central regions of a a subset of the UIT galaxy targets. Both Atlases will become available in 1998.
