The shell-type supernova remnant (SNR) RCW 86, possibly associated with the historical supernova SN 185, with its relatively large size (about 40 in diameter) and the presence of nonthermal X-rays is a promising target for γ -ray observations. The high sensitivity, good angular resolution of a few arcminutes and the large field of view of the High Energy Stereoscopic System (HESS) make it ideally suited for the study of γ -ray morphology of such extended sources. HESS observations have indeed
