Monoceros (The Unicorn)
- Monoceros is not very easily seen with the naked-eye, but often overlooked in favour of its glittering neighbouring constellations – specially Orion, but it lies in the Milky-Way.
- It contains some famous clusters and nebulae – Rosette Nebula, also the Open Cluster – Messier 50 (M50).
- Also the massive binary known as Plaskett’s Star.
- However, Monoceros does have some interesting features to observe with the aid of a small telescope. Beta Monocerotis is an impressive triple star system, the three stars forming a triangle which seems to be fixed.
- M50 – Open Cluster; remarkable objects – about half the apparent size of the Full Moon and easy visible in binocular.
Features of Interest
- NGC 2244 – The stars of Open Cluster (at the centre of this picture) are enveloped in the Rosette Nebula. The Open Cluster is easily visible through binoculars – however, excellent skies are needed to trace the outline of the surrounding Rosette Nebula which is four times larger to show up well only on photographs.
- NGC 2264 – Open Cluster; views through a small telescope it appears triangular in shape; also known as Christmas Tree Cluster or Cone Nebula.
- Alpha Monocerotis (Lucida)
