Abstract: We present "snapshot" observations with the Near-Infrared Camera and Multi-Object Spectrometer (NICMOS) on board the Hubble Space Telescope ( HST ) of 94 nearby galaxies from the Revised Shapley Ames Catalog. Images with 0 2 resolution were obtained in two filters, a broadband continuum filter (F160W, roughly equivalent to the H band) and a narrowband filter centered on the Paα line (F187N or F190N, depending on the galaxy redshift) with the 51 '' × 51 '' field of view of the NICMOS camera 3. A first-order continuum subtraction is performed, and the resulting line maps and integrated Paα line fluxes are presented. A statistical analysis indicates that the average Paα surface brightness in the central regions is highest in early-type (Sa-Sb) spirals.
