Quick Reference

A small disk placed centrally in the field of view of an eyepiece, or at the focal point of a telescope, to hide or occult a bright object so that fainter objects can be seen more readily. An occulting disk may be used, for example, to reveal faint satellites of a planet, or to hide the Sun's disk in a coronagraph.
