Abstract
We present images of 51 3CR radio galaxies with 0.5 < z < 2.5 obtained in the snapshot mode with the Hubble Space Telescope. The images are short exposures with the Planetary Camera and the F702W filter. A wide range of morphologies and surface brightness are seen on subarcsecond scales. Some are very strongly nucleated, and their light is most likely dominated by the nonstellar nucleus. Several galaxies have close companions or multiple components, while others have a close agreement between their optical/UV and radio sizes and orientations. These latter objects are primarily steep-spectrum doubles with angular sizes less than ~5''.Keywords
