With the aim to extend a sample of the distant radio objects, about 100 steep spectrum FRII radio galaxies (SS FRII RG) from the RATAN—600 RC catalog were mapped by the VLA1 and identified with optical objects down to R = 24m − 25m with the 6 m telescope. The mean estimated redshift of SS FRII RGs from the RC list happened to be greater than 1.5. BV RI photometry was made, and by standard model fitting we have estimated “colour” redshift and the age of stellar population of the parent gE galaxy in 50 cases. Several objects were found in which active star formation began in the first billion of years after the Big Bang.
