Abstract from DBPedia
    A coronagraph is a telescopic attachment designed to block out the direct light from a star so that nearby objects – which otherwise would be hidden in the star's bright glare – can be resolved. Most coronagraphs are intended to view the corona of the Sun, but a new class of conceptually similar instruments (called stellar coronagraphs to distinguish them from solar coronagraphs) are being used to find extrasolar planets and circumstellar disks around nearby stars as well as host galaxies in quasars and other similar objects with active galactic nuclei (AGN).

    コロナグラフとは、太陽コロナを常時観測できるように設計された望遠鏡、または観測装置。近年では、太陽以外の恒星の観測に用いられる恒星コロナグラフも存在する。
