Abstract

Flux-calibrated images in the lines of [O III] λ5007 and Hα + [N II] λλ6548, 6583 and the nearby continuum are presented for 57 Seyfert galaxies of early morphological type. This sample includes all known Seyfert galaxies with apparent magnitude m_v ≤ 14.5 and recessional velocity cz < 7000 krn s^-1 in Hubble types E, S0, and S0/a. Images are also presented for an additional 26 galaxies with m_v > 14.5, cz > 7000 km s^-1, and/or an uncertain classification as a Seyfert galaxy. The ratio of the [O III] λ5007 to the Hα + [Nn] image has been obtained for each galaxy with extended emission to study the spatial variation of the gaseous excitation. Maps of the V - R color distributions over the galaxies are also presented.
