There are several swans from Greek mythology identified with this constellation, including Zeus (who disguised himself as a swan to seduce Leda who subsequently gave birth to the Gemini), Orpheus (who was transformed into a swan after his murder) and King Cycnus (who turned into a swan after he was killed by Achilles during the Trojan War).
The asterism composed of the stars α Cyg, β Cyg, γ Cyg, δ Cyg and ε Cyg is often called the 'Northern Cross'. It is not to be confused with the much smaller constellation Crux, the Southern Cross.
|α Cyg||Deneb||This first magnitude star forms one part of the asterism known as the 'Summer Triangle'. It is also the top of the 'Northern Cross'.|
|β Cyg||Albireo||Albireo shows up as a beautiful binary star of constrasting colours when viewed through binoculars or a telescope.|
|ε Cyg||Gienah||The name of the star is not officially recognised by the IAU.|
|ω2 Cyg||Ruchba||The name of the star is not officially recognised by the IAU.|
|61 Cyg||Just visible to the naked eye, this is one of the closest stars to the Sun and the first one successfully observed for parallax.|
|M29||This is an open cluster, visible through binoculars.|
|M39||Binoculars are also required to see this open star cluster.|
|C15||Blinking Planetary||This is a planetary nebula visible through telescopes. The central star is quite bright but averted vision will reveal the nebulosity.|
|C19||Cocoon Nebula||The Cocoon Nebula requires optical aids to see this seventh magnitude combination emission/reflection nebula with accompanying star cluster.|
|C20||North America Nebula||The North America Nebula is so called because in long exposure it takes the outline of the North American continent.|
|C27||Crescent Nebula||A small telescope should reveal this faint emission nebula.|
|Veil Nebula||These objects are part of the Cygnus Loop complex, a supernova remnant. The star that blew itself to bits exploded 5000-8000 years ago.|
|Cygnus X-1||Probably a black hole, this object is one of the strongest x-ray sources in the sky. It can be found close to η Cyg on the sky map.|
