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.
