Sharpless 2-171, The Teddy Bear Nebula in Cepheus657 viewsAn emission nebula, part of a larger nebula designated NGC 7822, about 2900 light years away.

IC1396A - Elephant Trunk Nebula 652 viewsA narrowband (Hubble Palette) image of a dense cloud of gas and dust within a much larger region of ionized gas designated IC1396, illuminated and ionized by the massive bright star HD206267 at the upper right corner of the frame. I don't find that the shape of the nebula resembles an elephant's trunk, but rather, as Michelle Evans has suggested, a dragon named Verminthrax Pejorative from the movie Dragonslayer.

Sharpless 2-155 - The Cave Nebula635 viewsA narrowband (Hubble Palette) view of an emission nebula in Cepheus; part of an ionized HII region within a larger complex containing emission, reflection and dark nebulae. About 2400 light-years away, on the edge of the Cepheus molecular cloud.

NGC 7822 - Star-forming region in Cepheus621 viewsIncludes the emission nebula Sharpless 171 and the star cluster Berkeley 59. Around 3000 light-years from Earth.

NGC6992 - The Eastern Veil Nebula601 viewsPart of the Cygnus Loop, a supernova remnant in Cygnus. Also known as the Network Nebula.

NGC 6888 - The Crescent Nebula590 viewsAn emission nebula in the constellation Cygnus, about 5000 light-years away from Earth; formed by the fast stellar wind from the Wolf-Rayet star WR 136 colliding with and energizing slower-moving matter ejected by the star when it became a red giant around 250,000 to 400,000 years ago.

M20 - The Trifid Nebula589 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.

IC417 and NGC1931 - The Spider and the Fly585 viewsEmission nebula in Auriga, 100 light-years across and 10,000 light-years from Earth. The Fly (NGC1931) is about 7,000 light-years away.

Sharpless2-27 - The Zeta Ophiuchi Nebula584 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..

IC4604, The Rho Ophiuchi Nebula580 viewsPart of the Rho Ophiuchi complex, a gaggle of interstellar clouds centered 1 degree south of the star Rho Ophiuchi. Estimated distance from Earth is 460 light-years.

NGC6302 - The Bug Nebula577 viewsA bipolar planetary nebula in the constellation Scorpius. Also known as the Butterfly Nebula, but a larger telescope than the 5" refractor used to capture this image is needed to show the pattern clearly; it shows up well in Hubble images. In this image, the nebula looks more like a bug squashed on a car windshield.

IC4592, the Blue Horsehead Nebula577 viewsReflection Nebula in Scorpius, lit up by Nu Scorpii. About 400 light-years away.
