M8 - the Lagoon Nebula (narrowband)707 viewsA giant emission nebula in Sagittarius. Distance 4100 light-years. 110 x 50 light-years in size. Part of a larger star cloud.

IC 4604 - Rho Ophiuchi Nebula 706 viewsA blue reflection nebula in Ophiuchus, illuminated by three bright stars of which the central and brightest is Rho Ophiuchi. Lying along the border of Ophiuchus and Scorpius, this nebula and its neighbor IC4603 are close to the giant red star Antares.

Sharpless 2-64, emission nebula in Serpens706 viewsAn emission nebula in Serpens about 1000 light years distant. Dim and difficult to image. Sometimes called the Smoking Embers nebula.

IC 5067 - The Pelican Nebula705 viewsAn emission nebula (H-II region) in the constellation Cygnus, associated with the North American Nebula (NGC 7000), but visually separated from it by a dark dust cloud. Supposedly has the shape of a pelican, though not very much in this image.

Sharpless2-27 - The Zeta Ophiuchi Nebula702 viewsLarge but very faint emission nebula centered on the star Zeta Ophiuchi. Difficult to image because of the brightness of the star relative to the faintness of the nebula..

M20 - The Trifid Nebula701 viewsA combination of an open cluster of stars, an emission nebula (the lower, red portion), a reflection nebula (the upper, blue portion) and a dark nebula (which accounts for the gaps dividing the nebula into lobes). About 5000 light-years away in the constellation Sagittarius.

NGC 6992 - Eastern Veil Nebula700 viewsAlong with NGC 6960 and other objects, the Eastern Veil is a component of the Veil Nebula in the constellation Cygnus. It is a cloud of hot, ionized gas composed of oxygen, sulfur and hydrogen.

IC443 - Jellyfish Nebula697 viewsA galactic supernova remnant in Gemini, about 6000 light-years away.

NGC281 - The Pac-Man Nebula697 viewsA bright emission nebula, part of an H II region in the constellation Cassiopeia; known as the Pac-Man Nebula because of its resemblance to the video game character that flits around ruthlessly and insatiably chomping up defenseless, pathetic little dots.

NGC 7293 - The Helix Nebula in Aquarius696 viewsOne of the closest planetary nebulae, at only 650 light-years from Earth. Around 10,600 years old and 2.5 light-years in diameter. Sometimes known as the "Eye of God" or the "Eye of Sauron."

Gum 85/Sh2-54 - nebula in Serpens696 viewsGum 85/Sh2-54 is a star forming region in Serpens Cauda, part of the Serpens OB2 Association, a large star forming region possibly associated with the open star cluster NGC6604 (not in view). Around 5000 light years away.

Sharpless2-180693 viewsDiffuse emission nebula in Cassiopeia, quite dim
