NGC7380 - The Wizard Nebula730 viewsOpen cluster with surrounding nebulosity in Cepheus, about 8500 light-years away.

M78 - Reflection Nebula in Orion724 viewsM78 - Reflection Nebula in the Orion B molecular cloud complex, 1,350 light-years from Earth.

M8 - the Lagoon Nebula (narrowband)721 viewsA giant emission nebula in Sagittarius. Distance 4100 light-years. 110 x 50 light-years in size. Part of a larger star cloud.

M42 - The Great Nebula in Orion720 views1344 light-years away, 24 light-years across, this emission/reflection nebula is one of the brightest in the sky, as well as the closest region of massive star formation to Earth.

IC 4604 - Rho Ophiuchi Nebula 720 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 Serpens719 viewsAn emission nebula in Serpens about 1000 light years distant. Dim and difficult to image. Sometimes called the Smoking Embers nebula.

NGC1499 - The California Nebula, narrowband version717 viewsThis bizarre rendition of the California Nebula was the result of an unrepeatable experiment in mapping H-alpha and O-III to various channels in a mad orgy of improvisation.

Sharpless2-27 - The Zeta Ophiuchi Nebula717 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..

NGC281 - The Pac-Man Nebula716 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 6992 - Eastern Veil Nebula715 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 Nebula714 viewsA galactic supernova remnant in Gemini, about 6000 light-years away.

M20 - The Trifid Nebula713 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.
