The error circles of ten X-ray sources discovered since 1987 in the direction of the Galactic center, are investigated at optical and infrared wavelengths using Palomar sky survey plates, and deep photographic survey plates obtained with the UK Schmidt telescope at the Anglo-Australian observatory. The objects were cross-identified with the catalogs of variable stars, IRAS point sources and Einstein of X-ray sources in the sky region. As expected, very strong interstellar dust absorption is typical for all the X-ray source fields. Optical photographic reproductions of error circles and their neighborhood are presented, some stars with outstanding blue or red colors are marked.
