The paper contains preliminary results from a photographic study of 30 nearby galaxies (VR less than 5000 km/s). appearance these well-resolved objects suggests that the morphology both type 1 and 2 is characterized by three-step distribution in radial surface brightness disk. Superposed on this continuum spiral-like patterns, ranging sharp, distinct arms to diffuse, amorphous segments. An interpretation presented which nuclear activity fed gas disk disturbed structure found some Seyferts end product feeding. Analysis relation between inclination H-beta FWZI for sample may be correlated. However, an alternative larger values are associated with more Seyferts. space density discussed here appears greater previously ascribed objects.
