  The CFHT Adaptive Optics Bonnette (AOB) has been used to obtain high spatial
resolution (0.1") observations of several extragalactic targets including the
nuclei of nearby galaxies, high redshift galaxies, AGN, radiogalaxies, the host
galaxies of quasars and gravitational lenses. Examples of these are discussed
and the role of adaptive optics in exploring the high redshift universe is
critically assessed in light of these results.
