Scientific paper

We present new electronographic observations of three galaxies. We study the outer structure of NGC 4151 and trace the NE arm to larger distances than in previous works. We show that, at 1% of the sky brightness, there is a clear asymmetry in the envelopes of both NGC 1265 and IC 310. This asymmetry coincides with the radio tail direction of NGC 1265 but not with that of IC 310. We study the luminosity profiles of the three galaxies and find a deviation from de Vaucouleurs's reduced luminosity law in both NGC 1265 and IC 310, which indicates that both are supergiant elliptical galaxies.
