Cygnus (The Swan)

  • Feature constellation of Cygnus, often nicknamed “The Northern Cross”; its brightest star is Deneb (Magnitude: +1.3)
  • Deneb forms one corner of the Summer Triangle, with Vega in Lyra and Altair in Aquila. (See the photo.)
  • It lies in a rich part of the Milky Way.

Messier Objects

  • M29 – Open Cluster; similar to the Seven Sister (M45), M29 is ten times farther away and is much less famous than The Seven Sisters.
  • M39 – Open Cluster; Very large but very loose Open Cluster.

Features of Interest

  • NGC 7000 – North America Nebula; large nebula, visible under dark skies with binoculars or a wide field eyepiece for telescope – also known as Caldwell 20 (C20), the astrophotography takes the image that resembles the outline of North America map.
  • NGC 6826 – The Blinking Planetary; also known as Caldwell 15 (C15), is a planetary nebula – too bright with large telescopes to have the striking “blinking” effect seen with smaller telescopes.
  • NGC 6992 – The Veil Nebula; left behind by the explosion of a massive star thousands of years ago – a large supernova remnant as left over to be seen today in Cygnus.
  • Albireo – one of the great small-telescope showpieces in the sky; even low magnification views resolve it into a double star – brighter yellow star making a striking colour contrast with its fainter blue star. (Click me for location.)
