IC 4605 - The Blue Angel Nebula
Inside the Rho Ophiuchi Cloud Complex, in the constellation Scorpius, lies The Blue Angel Nebula. This is a reflection nebula with a very active star forming region embedded in the bright area just below center. The other stars that illuminate their surrounding gasses are brand new, hot stars. The region sits between 400-700 light-years away.

 		Sh2-308 - The Dolphin Head Nebula
Not far from Sirius, the Dog Star, in the constellation Canis Major, lies the Dolphin Head Nebula. It is located in a Ha region. The nebula began its life about 70,000 years ago as the star in the center blew off its outer layers as it began its pre-supernova phase of life, and is made up of mostly Hydrogen and Oxygen gasses. It sits about 4530 light-years away and 60 light-years wide. The center star (EZ Canis Majoris) is a Wolf-Reyet star which means that it is extremely hot an lumoinous. It is pushing the expanding gasses outward at roughly 3.8 million mph.

IC 59 (Sh2-185) - The Ghost of Cassiopeia
IC 59 is both an emission and reflection nebula situated in the constellation of Cassiopeia. It sits around 600 light-years from Earth. When imaged with RGB filters, it usually appears blue in color. However, this image was shot with narrowband filters (SHO) which allows the processing to be done in just about any color. The central star (Gamma Cassiopeiae) appears to be a circular blue planetary nebula. This is just an artifact of the gaseous materials in the area. IC 63 is directly below the central star, while IC 59 is at its 4 o'clock position.

This dark nebula is a molecular cloud and sits about 1000 light-years away from Earth in the constellation Cepheus. LDN stands for Lynd's Dark Nebula. Even though we can't see all of the star forming activity with visual telescopes, with radio and infrared we can peer into the interior to see that there are a considerable amount of new and forming stars there. The far right side of the nebula appears to have a bow shock wave, leading astronomers to believe that the entire nebula is moving through space at about mach 2.

Way out in the Perseus arm of the Milky Way is the constellation Cassiopeia. That's where this bright emission nebula resides. It sits about 9500 light-years away and has a diameter of about 96 light-years.

LDN 43 (Lynd's Dark Nebulae) - The Cosmic Bat Nebula
This dark nebula, in the constellation Ophiuchus, is a little deceptive in its appearance. The dark nebula that has the bat shape is actually in front of another, larger bright nebula behind it, which give it the look of a bat. The background nebula gives off enough light to contrast it against the background, but the bright areas inside the nebula are due to stellar nurseries where numerous new stars have, and are forming. It sits about 1400 light-years away and is about 9 light-years wide.

Barnard 7
Barnard 7 is a dark nebula in the constellation Taurus, and is part of the larger Taurus Molecular cloud Group. 





Image processed by Ron Yelton, original data from Telescope Live   		CG 4 - God's Hand
This star forming region is located in the constellation Puppis. It sits about 1300 light-years away. The head area is about 1.5 light-years across and the tail section stretches about 8 light-years long. Although it appears to be a dark nebula, it is officially classified as a Cometary Globule, due to its comet-like shape. To me it looks more like one of the worms from the movie Dune as it reaches out to grab that nearby galaxy.

LDN 43 - The Cosmic Bat Nebula
What a cool bat! This one is a dark nebula that is lit up from the inside by hot, young stars. The exterior is lit by nearby LDN 7, another stellar nursery. From wingtip to wingtip it is about 12 light-years across. It sits about 1400 light-years away in the constellation Ophiuchus. This one and the next two were taken with a wide-field camera (382mm), I zoomed in a couple of times. The Cosmic Bat a couple of rows above was taken with the 24" PLanewave.

Sh2-103 - The veil Nebula
The Veil Nebula is just a small part of the much large Cynus Loop. It consists of may sub-objects with their own names and designation numbers. It was formed when a star about 100 times the size of Earth went supernova between 10,000 and 20,000 years ago. This version was post-processed in the HOS palette.

NGC 2736 - The Pencil Nebula
This nebula is just a very small part of the larger Vela Nebula, which is a Supernova Remnant. It is located in the constellation Vela. It sits about 815 light-years away from us and is thought o have been formed as a result of the leading shock-wave from the expanding supernova gas. It is moving along at a comfortable 400,000 mph.
