IC2177 - The Parrot Nebula665 viewsUsually known as the Seagull Nebula, but to me it looks more like a parrot. An HII region lying along the border between Canis Major and Monoceros.

NGC6960 - The Western Veil Nebula663 viewsPart of the Cygnus Loop, a supernova remnant in Cygnus. Also known as the Witches’ Broom.

Sharpless2-1661 viewsCombination of a diffuse HII emission nebula and reflection nebula in the constellation of Scorpius with Pi Scorpii at its center.

NGC2359 - Thor's Helmet660 viewsAn emission nebula in the constellation Canis Major. About 12,000 light-years distant and 30 light-years in size. Associated with the Wolf-Rayet star WR7.

NGC7635 - The Bubble Nebula - H-alpha enhanced version658 viewsAn emission nebula in the constellation Cassiopeia. The "bubble" is created by the stellar wind from a hot, massive star within a molecular cloud which contains the expansion of the bubble, preventing it from dissipating, and is also itself excited by the star. The nebula is 7 light years across and 7100 light-years away.

Tulip Nebula - Sh2-101657 viewsAn emission nebula about 6,000 light-years away in the constellation Cygnus. The shape vaguely resembles the outline of a tulip.

NGC 1977, The Running Man Nebula in Orion657 viewsA reflection nebula embedded in a bright HII region, Sh2-171, found in Orion's Sword near the Great Orion Nebula M42. Sh2-171 also includes two other nebulae and the star cluster NGC-1981.

NGC2237 - The Rosette Nebula652 viewsEmission Nebula / HII region in Monoceros, with open cluster NGC 2244 in center of nebula.

M8, the Lagoon Nebula, and M20, the Trifid Nebula651 viewsTwo jewels of the summer sky captured in the same frame with a bridge of nebullosity between them.

M20 - the Trifid Nebula (narrowband)649 viewsAn emission/reflection nebula in Sagittarius. About 4100 light-years from Earth.

NGC 7023, the Iris Nebula645 viewsReflection nebula in Cepheus. Actually the nebula is LBN 487, and NGC 7023 is a star cluster within the nebula. 1300 light-years away and 6 across.

NGC 2359 - Thor's Helmet644 viewsAn emission nebula in the constellation Canis Major; about 12,000 light-years away. Consists largely of interstellar gas swept up by the central star, and partly of material from the star itself, which is an extremely hot, massive Wolf-Rayet star in a short-lived pre-supernova stage.
