This cropped image of the beautiful complex of bright red emission nebulae, blue reflection nebulae and black dark lane B303 is to the east of M8 Lagoon nebula in the Sagittarius summer Milky Way. This is a joint project of James Foster and me from Frazier Park California using my Askar 103 APO refracting telescope.
