Sharpless2-180709 viewsDiffuse emission nebula in Cassiopeia, quite dim

Gum 85/Sh2-54 - nebula in Serpens707 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.

NGC2264 - Christmas Tree Cluster/Cone Nebula705 viewsBoth a cluster and a nebula, NGC2264 is located in the constellation Monoceros, 2,300 light-years from Earth.

M42 - The Great Nebula in Orion704 viewsA narrowband image of the Orion Nebula, captured with a one-shot color CMOS camera and an IDAS NBZ nebula enhancement filter.

The Horsehead Nebula in Orion701 viewsThe Horsehead Nebula, Barnard 33, is a dark nebula, silhouetted against the bright emission nebula IC 434. The large blue object to the left of IC 434 is a reflection nebula, NGC 2023. They are all found near the star Alnitak, the easternmost star in Orion's belt, which is off the frame to the right, and are 1400 light-years from Earth.

NGC6334 - Cat's Paw Nebula701 viewsAn emission nebula and star-forming region in the constellation Scorpius; distance from Earth is about 5500 light-years. Also known as Gum 64 or the Bear Claw Nebula.

Sh2-119 - the Clamshell Nebula700 viewsLarge emission Nebula in Cygnus, located around the bright star 58 Cygni. The frame is only large enough to accommodate a small part of the left side of the clamshell.

Sh2-204 - Faint nebula in Camelopardalis699 viewsEmission nebula, about 12,500 light-years away

Sharpless2-13697 viewsEmission nebula in Scorpius.

Sharpless2-112697 viewsEmission nebula in Cygnus, energized by the star BD +45 3216 embedded within it.

IC1805 - The Heart Nebula, narrowband version695 viewsNarrowband rendition of the Heart Nebula, using the IDAS NBZ nebula enhancement filter to capture the H-alpha and O-III emissions; Fish Head Nebula seen as extension of Heart at lower left.

NGC 6543 - Cat's Eye Nebula694 viewsA structurally very complex planetary nebula about 3000 light-years from Earth in the constellation Draco. In large-telescope images it has the appearance of a cat's eye, but in my 5" refractor it appears simply as a bright blue star with a halo. The small spiral galaxy off to the left is probably NGC 6552.
