Astronomers have partially solved the problem of looking at objects near to a star's bright glare by inventing the coronagraph, which focuses all the incoming light around a dark spot in the telescope's innards, neatly clipping off most of the central starlight and passing on much of the planetary glow.

天文学家用日冕仪一定程度上解决了观测恒星强光附近物体的难题。日冕仪精巧地阻挡了进入望远镜中央区域的绝大部分恒星光，让更多的行星光进入望远镜。这样一来，日冕仪就能专注于分析望远镜内部圆形黑暗区域周围的入射光。
