... As a result of the BTA spectroscopy of a faint optical source (R=23), earlier identified at the BTA with a compact ( RC J0311+0507 from the sample of objects with ultra-steep radio spectra (RATAN-600), a radio galaxy with a strong narrow emission line, the most likely identification of which is the Lyman-alpha hydrogen at redshift of z=4.514. This is the second radio galaxy, discovered at a redshift of more than 4.5 - a real candidate for the most powerful radio objects of the Early Universe. ...

On April 8, 2005, an optical afterglow of the GRB 050408 was discovered with the SAO's telescopes (the 1-meter telescope Zeiss and 6-meter telescope BTA) within the framework of a joint BTA request (SAO RAS + IAA CSIC, Granada, Spain) on optical identification of gamma-ray bursts. We first detected a variable object only by our own data in the localization error-box reported by the space observatory HETE and then it was confirmed by our observations in SAO. ...
