Denebĭeneb, Alpha Cygni, is the star at the top of the Northern Cross. Deneb (Alpha Cygni), Albireo (Beta Cygni), and Sadr (Gamma Cygni) form the pole of the cross, while Fawaris (Delta Cygni) and Aljanah (Epsilon Cygni) mark the cross beam. The stars that form the Northern Cross are Alpha, Beta, Gamma, Delta, and Epsilon Cygni. It is most readily seen in the summer, when it rises in the east at sunset, climbs directly overhead after midnight, and moves to the west by sunset.ĭeneb marks one end of the “Great Rift” in the Milky Way, a series of dark clouds that stretch all the way to the centre of our galaxy in Sagittarius constellation in the southern sky. In the northern hemisphere, the cross-shaped pattern is visible for at least part of the night throughout the year. The Northern Cross lies in the direction of the Milky Way’s disk, and the galactic plane (equator) runs through the asterism. Once you find Deneb and Albireo, it is easy to make out the pattern of the Northern Cross. Albireo is located roughly halfway from Altair to Vega and slightly offset toward Deneb. It is not as bright as Deneb, but can easily be seen without binoculars on a clear night.
