Delphinus, the Dolphin, is a small northern constellation, lying just north of the celestial equator between Pegasus and Aquila. Its four main stars, none brighter than third magnitude, form an asterism known as Job's Coffin. Gamma Del is a wide double that can be resolved by binoculars, magnitudes 4.5 and 5.5. The region around Delphinus has been an unusually rich hunting ground for novae. See below for details of the constellation's brightest stars and interesting deep sky objects.
