Abstract / Description:In April 2010, a new coronagraphic optical element, called an Apodising Phase Plate (APP), was installed in NAOS-CONICA (NACO). The APP coronagraph is optimised for use at 4.05 µm with both narrow- and broadband filters. Unlike other types of coronagraph, it requires no alignment overhead and can be used immediately after switching from direct imaging for observing targets of interest where high contrast is required.
