Some of us carried out a pilot project in Cycle 1 to observe two distant galaxies known, 4C 41.17 at z = 3.8 and 4C 28.58 at z = 2.9. These redshifts correspond to relative lookback times of between 80% must be close to the epoch at which the galaxies formed. The pilot project was successful. The ultraviolet continua of galaxies were well detected and exhibit clumpiness on a scale of hundred parsec. The morphologies help constrain models of the radio/optical alignment effect observed in distant radio galaxies indicate that the optical structure has scales that are ideally to mapping with the HST. There are several important differences between the the two detected objects. Here we propose expanding our sample by imaging 2 additional galaxies to search for trends and relate them to models of the emission. The observations are also preparatory to a statistical study of a large sample of distant radio galaxies which we hope to after refurbishment. This will investigate the continuum and morphologies and their redshift dependance. It will provide information about (i) radio galaxy formation and evolution, (ii) environment of the z > 2 Universe and (iii) cosmological models.
