CYGNUS

Cygnus, the celestial Swan, flies toward lower right and to the horizon, great Deneb, seen toward the upper left, marking its tail. Albireo, down and to the right, marks the Swan's head, Sadr, just up and to the left of center, its breast, Gienah Cygni (down and to the left of center) the east wing, and Delta Cygni the west wing. Zeta is down toward bottom left. Cygnus reversed becomes the Northern Cross, Deneb now at the top, Albireo at the foot, the arms of the cross stretching from upper right to lower left, Sadr at the intersection. The "luminous blue variable" P Cygni is just down and to the right of Sadr, while 61 Cygni is the right hand star of the triangle at far left center. The Mira variable Chi Cygni, which lies well up and to the left of Albireo, is here too faint to be seen. The "Omicrons" are at top center, Omicron-2 (32 Cygni) on top, Omicron-1 (31 Cygni) at the bottom. Just to the upper right of Omicron-1 and barely resolved from it is 30 Cygni. The black hole binary Cygnus X-1 is near the center of the picture, and can be seen on the deep image. The Milky Way is faintly visible in the background. Deneb lies at the northeastern apex of the Summer Triangle.
