Paper Abstract

We outline the concept and laboratory results of our coronagraphic testbed which has been shipped on automn 2005 to Dome C in Antarctica. We also describe the principle of our coronagraph achromatization and the laboratory first data like the coronographic nulling results which attain more than 103 at least. The future development of our experiment for a much larger telescope is also outlined. We finally present CORONA's on-sky first results.
