NGC2359 - Thor's Helmet641 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.

NGC 1977, The Running Man Nebula in Orion640 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.

NGC6960 - The Western Veil Nebula638 viewsPart of the Cygnus Loop, a supernova remnant in Cygnus. Also known as the Witches’ Broom.

Sharpless2-275 - The Rosette Nebula637 viewsHII region in the constellation Monoceros; distance 5,200 light-years from Earth. Open cluster NGC2244, in the doughnut hole, provides the energy that makes the nebula glow.

Tulip Nebula - Sh2-101635 viewsAn emission nebula about 6,000 light-years away in the constellation Cygnus. The shape vaguely resembles the outline of a tulip.

M8, the Lagoon Nebula, and M20, the Trifid Nebula633 viewsTwo jewels of the summer sky captured in the same frame with a bridge of nebullosity between them.

Sharpless2-1633 viewsCombination of a diffuse HII emission nebula and reflection nebula in the constellation of Scorpius with Pi Scorpii at its center.

M42 - The Great Nebula in Orion631 viewsAnother take on the Great Orion Nebula, incorporating hydrogen-alpha data.

M20 - the Trifid Nebula (narrowband)631 viewsAn emission/reflection nebula in Sagittarius. About 4100 light-years from Earth.

NGC2237 - The Rosette Nebula625 viewsEmission Nebula / HII region in Monoceros, with open cluster NGC 2244 in center of nebula.

IC1848 - The Soul Nebula, narrowband version625 viewsNarrowband rendition of the Soul Nebula, captured using an IDAS NBZ nebula enhancement filter, with H-alpha emissions in red and O-III emissions in blue.

NGC 7023, the Iris Nebula625 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.
