The stellar coronograph built by STScl and the OATO operating at the SUSI focus of ESO's New Technology Telescope (NTT), described with particular emphasis on its optical and mechanical characteristics, is one of the most powerful coronographs in operation. Observations with angular resolutions of 0.6 arcsec over field of view of 45 arcsec diameter have been routinely achieved in the observing runs carried out so far. We describe the results from the application of the coronograph to the problem of observing the inner regions in the (beta) Pictoris dust disk.
