The Advanced Camera for Surveys (ACS) offers a coronagraphic imaging mode with angular resolution of 0.026"pixel-1. In combination with with the appropriate subtraction of reference star point spread functions (PSF) the coronagraph is capable of achieving contrast ratios of '"'-'1000. We present some of the first ACS observations of the optically thin debris disk HD141569A and discuss new results from these observations.
