Swells of Hydrogen-alpha emission at left frame this vista of a pair of emission nebulae — Sharpless 2–115 at upper right, and the small planetary nebula Sh 2–116 at lower right. “I like the sense of depth the different cloud structures give to the image,” the photographer writes. “As a viewer it looks like you are ascending or descending into the nebula.” The shot was taken with 17 hours of exposure in SHO and RGB filters with a 6-inch f/4 scope.
