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.
