Description

We discuss the first results of the optical identification the SRG X-ray sources of the 18.5 square degrees Lockman Hole PV-phase survey. We show first spectroscopically confirmed quasar candidates at z~4 the spectra of which were obtained at the 1.6-m telescope AZT-33IK and the 6-m telescope BTA.
We review a fraction of optical identification of X-ray sources in the several wide field broad band photometric surveys: SDSS, Pan-STARRS, DESI Legacy Survey.
