Walter's list (1990A&amp;AS...86..357W) was created. The coordinates of 12495 stars was obtained from the photographic plates of Pulkovo Normal Astrograph (NA, 33/346), which was photographed in 1994-1999 years. Size of worked fields (radius about 20-40 angular seconds) was determined from the resolved problem and having technical resources: modern dimensions of CCD-detector. Precise astronometric coordinates of stars were intending for optical control beyond the positions of radio sources (GRS) by means of CCD-observation. The galactic radio stars can be the frames at the definition of connection between the existed ground and cosmic astronometric reference coordinate sets. Coordinate calculation was realization with used reference stars from catalogue Tycho-2 (ICRF, J2000.0). Error of a unit of weight from reduction coordinates was resulted nearly 0.12"-0.27" (at a number of reference stars were from 12 to 50). Internal precision of catalogue was obtained from 0.02 to 0.20 arcseconds at the both coordinates.</description><source
