1. The Spectrophotometrical complex in Nasmyth-1 focus
The spectrophotometrical complex of the 6-m telescope in Nasmyth-1 focus . ... A new sample of 360 blue compact galaxies with a strong star formation was build on the base of the Second Byurakan Survey. ... More that 20 galaxies with the extremely low-abundances of heavy elements in the range of 1/30-1/10 of the Sun's one, were found. ... During the 15-years observation term near 500 spectra of the unique source SS~433, from which the relativistic jets were found for the first time, were obtained. ...
