SUMMER TRIANGLE SETTING

The first magnitude stars of the setting Summer Triangle are all seen in context: Vega in Lyra toward the lower right of the image, Deneb in Cygnus to the upper right, and Altair in Aquila to the lower left. Sagitta is up and to the right of Altair, while Delphinus lies above the star. Equuleus and Pegaus are to the far left, Draco to the far upper right. The Milky Way, with its dark Great Rift, runs from top to bottome through the picture. Epsilon and Zeta Cyg point leftward to Kappa Pegasi. Just up and to the right of it is the combined image of Mu-1,2 Cygni. Psi Cyg is the leftmost of the pair of fainter stars to the right and a bit down from Deneb. The three fairly bright stars in a row to the right and a bit up from Delta are from right to left Theta, Iota, and Kappa Cyg. The faint star between Iota and Kappa is Iota-1 (7 Cyg), rendering Iota Iota-2.
