                                   ABSTRACT

        Continuum-subtracted Halpha images of 17 nearby Seyfert galaxies
     are presented.  The images are calibrated astrometrically using the
     Hubble Space Telescope Guide Star Catalog reference frame.  For each
     galaxy, an inventory of H II regions detected using the COSMOS image
     classifier and centroider is provided.  Salient features of each
     galaxy are described, including the distribution of the H II regions
     with reference to the galaxy morphology.  Relevant abundance data from
     the literature are noted for each object.  These images will find use
     as finding charts for follow-up spectrophotometric investigations of
     abundances, abundance gradients, and kinematics of H II regions in
     active galaxies, and for detailed studies of H II region populations
     in these objects.
