Abstract
This report continues a series of papers discussing a complete high spatial resolution imaging survey of the highest redshift 3CR radio galaxies. CCD observations of seven 3CR galaxies with redshifts between 1.176 and 1.841 are presented. Excellent seeing conditions facilitated resolution of most of the galaxies into multiple components. Two of the galaxies are located less than 4 arcsec from a foreground bright galaxy; it is suggested that they may be gravitationally amplified by more than one magnitude. One of the objects, 3C 194 at z = 1.779, is proposed as a gravitational lens candidate. For the other galaxies observed, different interpretations are considered. The use of the high-redshift 3CR radio-galaxies as standard candles for cosmological purposes without further precautions is questioned. 30 references.
