Sagitta  (The Arrow)

  • This tiny constellation, Sagitta, is easy to find halfway between Altair in Aquila (The Eagle) and Albireo (Beta [β] Cygni) in Cygnus (The Swan).
  • It lies completely within the Milky-Way.
  • There is one globular cluster (M71) and one open cluster (H20), also three planetary nebula (NGC 6879, NGC 6886 & IC 4887).

Messier Objects

  • M71  –  Globular Cluster  –  small and faint stars, now generally regarded as a poor, weak concentrated globular cluster, rather than a rich open cluster; hazy spot in binoculars and small telescopes – ideally requires at least 6-inch telescope for best resolution.

Features of Interest

  • H20Â Â – Â Open Cluster; also known as Havard 20 (Magnitude: +7.7) – close to Messier 71 (M71 – Globular Cluster).
  • NGC 6879Â Â – Â Planetary Nebula; faint (Magnitude: +12.5), which is difficult to locate. Faintly visible from 6-inch telescope.
  • NGC 6886Â Â – Â Planetary Nebula; slightly brighter (magnitude: +11.4), but still a testing object – fairly easily seen with 6-inch telescope.
  • IC 4997Â Â – Â Planetary Nebula; bluish in colour and forming a obvious to your eye in mind to see pair with a yellow star.
