Scientific paper

CFH Telescope observations with the High-Resolution Camera of the central region of the boxy radio galaxy NGC 7052 in the R band reach the resolution of FWHM = 0.33 arcsec. This makes it possible to trace the structure of the dust previously detected in the central region of this galaxy. The dust is confined in an extremely sharp lane seen almost edge-on, about 0.3 arcsec away from the center and located along the projected major axis of the galaxy. The transverse size of the lane has a FWHM of 0.40 arcsec, and thus is not resolved by the observations. The angle with the radio axis is found to be 50 deg. Tracing very accurately the dust absorption profile made it possible to estimate the (small) amount of absorption at the center, and to derive core properties reliably corrected for dust absorption.
