Constellation of Cygnus, the Swan, in the northern summer sky, showing the variety of colours in the starclouds and nebulas that populate this section of the Milky Way. The red and pink emission nebulas of the North America nebula (NGC 7000), at left, and the Butterfly nebula (IC 1318), at centre, dominate. The small red patch at right in the Tulip nebula, Sh2-101. But the starclouds themselves go from being bluish at left, to more neutral at centre where the main Cygnus starcloud shines brightest, to yellowish at right in southern Cygnus and northern Aquila, where obscuring dust tints the starlight a warm tone. Other nebulas in this view include the purple Cocoon nebula (IC 5146) at far lower left at the end of the B168 dark lane, and the magenta arcs of the Veil nebula complex (NGC 6992-5 and NGC 6960) at bottom centre. Numerous large star clusters show up, notably NGC 6940 and smaller NGC 6885 to the right of the Veil. NGC 6811 (centre top) and NGC 6819 (to the right) are at top. The field is laced with dark nebulas, as this is the area where the Great Rift begins in the Milky Way, formed from dust lanes that split the visible Milky Way. The most prominent dark nebula is the Funnel Cloud nebula, or Le Gentil 3, at left, and the Northern Coal Sack beside and framing the North America nebula. Deneb is left of centre; at centre is Gamma Cygni, or Sadr. Albireo is at far right, above centre.
