A wide-angle CCD camera.

The North America Nebula (NGC 7000) is a region of ionized hydrogen in the constellation Cygnus. A lane of dark dust superimposed on the glowing hydrogen gives the appearance of the U.S. East Coast and the Gulf of Mexico. This is one of the first pictures made with a new camera designed for studies of Halley's comet by George Herbig and Burt Janes of the Lick Observatory in Santa Cruz, Calif. The camera combines the high light sensitivity of charge-coupled-device (CCD) photosensors with a wide field of view (4' by 6.5[deg.]) that CCD cameras have heretofore lacked. The picture was taken by Rich Pogge.
