Scientific paper

Optical imaging data are presented on 28 low redshift QSOs with 0.5 arcsec resolution. The group includes a range of radio and IR luminosities. The high-resolution data reveal significant new morphological information on 16 objects, and yield good luminosity profiles on all of them. Most objects appear to have R exp 1/4 law or peculiar luminosity profiles. The QSOs are almost all found to be in merging or interacting galaxies, most of them with a smaller companion. The observed structural details appear to be similar to lower luminosity AGN at low redshift. There are few unexplained features such as 'jets' near the nucleus. Detailed descriptions are given of all objects, including new high-resolution radio observations of a few of the QSOs.
