Abstract
Optical emission line images and spectra of sixteen 3CR powerful radio galaxies and quasars are presented. Extended line emission is detected in both radio galaxies and quasars. We show that line luminosities, derived from the spatially integrated [OII]lambda 3727 narrow emission line, are on average similar for radio galaxies and quasars of the same radio power and redshift. This result supports the unified model of these powerful radio sources, and indicates that the narrow line region contains dust.
