NGC 2024, The Flame Nebula, burns brightly in Orion the Hunter. At right is the brilliant blue giant star, Alnitak, 28 times the mass of our sun. Shining with a brightness 100,000 times that of the sun, Alnitak, is actually a triple star system in which two smaller blue stars orbit the behemoth. This false color image was formed from nine stacked frames of three minutes each binned 2 x 2, taken through narrow band Hydrogen alpha filter at focal length of 1480 mm, f/6.3. Image scale was 1.51. arc seconds per pixel.
