Orion Closeup

Objects visible in this photo include:
  • The seven named stars in Orion: Betelgeuse, Rigel, Bellatrix, Saiph, and the "belt" stars Alnitak, Alnilam, and Mintaka.
  • M 42 and M 43, the Orion Nebula.
  • Bright nebula M 78.
  • Open clusters NGC 1981 and Collinder 69. Note the large, faint red nebulosity around Collinder 69.
  • Barnard's Loop, an enormous arc-shaped structure that is difficult to observe visually but relatively easy to capture on film.
  • The red nebulosities around Alnitak (zeta Orionis): NGC 2024 and IC 434.
  • The detail at right shows the famous Horsehead Nebula (B 33). It is barely visible as a small, dark feature against the background of bright nebula IC 434.
