Cygnus, Lyra, Aquila are constellations that rise high above the horizon in the summer in a southerly direction. On the "tail" of the constellation Cygnus is its main star Deneb. In the constellation Lyra, the star Vega shines brightly. Altair is the brightest star in the constellation Aquila. The named stars form a summer-autumn triangle - a recognizable asterism of the Northern Hemisphere of the celestial sphere.
