Orion (The Hunter)
- Orion, perhaps the most magnificent of all the constellations.
- It’s located on the celestial equator, and visible throughout the world – most recognisable constellations in the night sky.
- Its brightest stars are Beta (Rigel);Â a blue-white, and Alpha (Betelgeuse);Â a redÂ supergiantÂ respectively. Many of the other brightest stars in the constellation are hot blue supergiant stars.
- TheÂ Orion Nebula, also known as Messier 42 (M42),Â is located south ofÂ Orion’s belt, in its lying Theta, a multiple star known as the Trapezium.
- M42 Â – Â Diffuse Nebula; visible to the naked-eye, and hazy spot in binoculars and small telescopes. Â The glowing hydrogen gas has a highly classified pinkish colour that is evident in the photographs, even those taken with few seconds exposed.
- M43 Â – small patch of nebulosity just north of the main body of M42 and visible under good conditions in binoculars. Â In fact it’s nothing more part of the whole Orion Nebula complex.
- M78 Â – Reflection Nebula; around magnitude: +8.0, lighted by two hot stars, all visible with 3-inch telescopes.
Features of Interest
- NGC 1981 Â – Â Open Cluster; detectable with the naked-eye, but so few stars that it does not bear much magnificaton; better with low powers, or binoculars.
- NGC 2024 Â – Â Gaseous Emission Nebula with dark dust lanes; very close to very Â bright star – Alnitak in Orion’s Belt, which should be kept outside the field of view. This emission is hard detectable with binoculars, and the dark lanes with 5-inch telescopes.
- NGC 2169 Â – Â Open Cluster; small consisting of around 30 stars.
