Orion’s Belt Region - Here’s another shot from last night’s imaging with the #WilliamOptics SpaceCat51 Apo Refractor and #ZWO 071MC cooled camera, a wide-field shot with all three primary stars in Orion’s Belt or the Three Sisters, Alnitak, Alnilam and Mintaka. I say “primary” because Alnitak (bottom one in this rotation) is a triple-star system, Alnilam (in the middle) is a supergiant on it’s own and is 375,000 times more luminous than our star, the Sun. Mintaka (top) is a double-star system and the two stars orbit each other every 5.7 days. So yeah, I’d like to see that up lose–two massive stars spinning around each other that quickly. Bottom right you can see the Horsehead Nebula (Barnard 33) and NGC 2024, the Flame Nebula to the left and a bit lower than the Horsehead with Alnitak between them. https://SaltwaterWitch.com
