DescriptionHere's an interesting juxtaposition of what appear to be two toroid-shaped planetary nebulae with layers of concentric outer shells: The little dumbbell M76 on the left appears edge-on, while the ring nebula M57 on the right appears face-on. M76 was imaged in December using narrow band HA and OIII filters while M57 was imaged in August with a combination of HA and RGB filters.
