This image shows you vast diffused nebulae surrounding a constellation of Orion. You can identify the "Great Orion Nebula" (M42) at the south of Orion's belt, the "Horsehead Nebula" near the zeta Ori, etc. And it's attracted the attention on a supernova remnant of "Barnard's Loop" encircling the eastern region of Orion's body. You can also see the oval "Angel fish Nebula" at the head of Orion. Almost all of these nebulae are emitting the H-alpha light from the activated hydrogen that cannot be detected by our naked eyes.
