CORONA: First Light at Dome C of the Antarctica Prototype APKC Coronagraph

International audience We present the results of the first light of CORONA obtained during the summer campaign 2005 at Dome C. The CORONA experiment uses an automated 14primeprime antarctized telescope for its remote operation from the Concordia station. The instrument includes an Achromatized Phase...

Description
Summary:International audience We present the results of the first light of CORONA obtained during the summer campaign 2005 at Dome C. The CORONA experiment uses an automated 14primeprime antarctized telescope for its remote operation from the Concordia station. The instrument includes an Achromatized Phase Knife Coronagraph (APKC) with no tip-tilt correction. The high contrast long exposure is obtained from image selection among raw short exposures.
