Scientific paper

CCD images of a volume- and luminosity-limited sample of 51 Markarian and NGC Seyfert galaxies show that Seyfert galaxies nearly always possess mechanisms for transporting material into their nuclei. A subset of Seyfert galaxies with amorphous morphologies, some of which may be remnants of past interactions, constitutes approximately one-fifth of the sample. The colors and exponential disk parameters of Seyfert galaxies are generally similar to those of spiral galaxies without active nuclei. Images of the galaxies are presented along with aperture magnitudes.
