This picture has captured the area of the Barnard's Loop spread at whole of Eastern Orion and the Rosette Nebula in the constellation of Monoceros with a medium ranged telephoto lens. This celestial field is mainly occupied with the area of Monoceros with a faint winter's Milky Way crossing slantingly. Though these diffused nebulae can be hardly seen with naked eyes, they're very photographed.
It's considered that the Barnard's Loop is a remnant of supernova exploded about one million years ago. It's a star's remains, and it would be reversely said that the Rosette Nebula is a cradle of stars, because the nebula includes the dark gaseous lumps called globules and new stars are under being born from them. There is a dynamic metempsychosis in the cosmic world although we cannot recognize that during our lifetime.
