We have carried out optical observations of the regions of the two hard X-ray/gamma-ray sources 1E 1740.7-2942 and GRS 1758-258. For GRS 1758-258, we have derived an accurate position using the data from the ROSAT All-sky Survey. Although both sources have small error boxes, their optical identification is hampered by the crowding of these low Galactic latitude fields, and by the heavy interstellar absorption. Here we present images in the filters I and Gunn's z, which appear the deepest so far of these regions. Several new candidates are revealed, one of which lies at only 2 arcsec from the suggested radio counterpart of 1E 1740.7-2942.
