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).
- 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
- H20 – Open Cluster; also known as Havard 20 (Magnitude: +7.7) – close to Messier 71 (M71 – Globular Cluster).
- NGC 6879 – Planetary Nebula; faint (Magnitude: +12.5), which is difficult to locate. Faintly visible from 6-inch telescope.
- NGC 6886 – Planetary Nebula; slightly brighter (magnitude: +11.4), but still a testing object – fairly easily seen with 6-inch telescope.
- IC 4997 – Planetary Nebula; bluish in colour and forming a obvious to your eye in mind to see pair with a yellow star.
