NGC 7000, commonly known as the North America Nebula, is a large emission nebula located in the constellation Cygnus. Its popular name derives from its distinctive shape, which closely resembles the continent of North America. The nebula is situated near Deneb, one of the brightest stars in the nigh...
Sharpless 2-276, commonly called Barnard's Loop, is a large emission nebula forming a broad arc around much of the Orion constellation. The glowing structure consists primarily of ionized hydrogen and spans roughly ten degrees of the sky, making it far larger in apparent extent than the Orion Nebula...
IC 1318 is a diffuse emission nebula complex located in the constellation Cygnus, situated near the bright star Sadr, also known as Gamma Cygni. The complex consists of dark dust lanes and glowing gas that are part of the larger Cygnus star-forming region. Although it appears surrounding Sadr from E...
Sharpless 2-292 is IC 2177, the Seagull's Head, an H II region on the Monoceros and Canis Major border discovered by Isaac Roberts.
The Lambda Orionis Ring is the large molecular cloud and H II shell around Lambda Orionis in Orion, spanning about 8 degrees on the sky.
Sharpless 2-129 is the Flying Bat Nebula, a large Cepheus H II region in the Cep OB2 association that contains the bipolar outflow nebula Ou4.
Sharpless 2-264 is an H II region in Orion, ionized by Lambda Orionis and cataloged in Stewart Sharpless's 1959 survey of Galactic nebulae.
Sharpless 2-126 is the Great Lacerta Nebula, a large H II region in Lacerta ionized mainly by the O-type star 10 Lacertae.
Sharpless 2-119 is the Clamshell Nebula in Cygnus, a ringlike H II region ionized by the rapidly rotating O star 68 Cygni.
Sharpless 2-115 is a Cygnus H II region northwest of Deneb, cataloged by Stewart Sharpless in 1959 and ionized by Berkeley 90.
Sharpless 2-124 is a large Cygnus H II region linked to V645 Cygni and RAFGL 2789, with infrared sources, masers, and active star formation.
