The binary star [[Albireo]] (Beta Cygni) represents the head of the swan. The tail is where the brightest star of the constellation, [[Deneb]], is located. Deneb is also the tip of the Northern Cross and the upper-left corner of the [[Summer Triangle]]. The dim binary star [[61 Cygni]] also lies within the constellation and is the closet star within it, only some 11.4 light years away, and is famous for being the first star to be measured using [[parallax]].

Cygnus is also the location of several notable deep sky objects, including numerous diffuse and [[planetary nebula|planetary nebulae]], and [open star cluster|open star clusters]]. The '''Fireworks Galaxy''' (NGC 6946) is also located here, known as the most active supernovae galaxy known. Another galaxy is '''Cygnus A''', one of the strongest astronomical [[radio]] sources known. '''Cygnus X-1''' is another astronomical feature within the constellation and is famous for being one of the greatest known sources of [[x-ray|x-rays]].<ref name="seds">http://seds.org/Maps/Stars_en/Fig/cygnus.html</ref>
