NGC 6888 Crescent Nebula

Wikipedia describes this object as follows: "The Crescent Nebula is an emission nebula in the constellation Cygnus, about 5000 light years away. It is formed by the fast stellar wind from the Wolf-Rayet star WR 136 (HD 192163) colliding with and energizing the slower moving wind ejected by the star when it became a red giant around 400,000 years ago. The result of the collision is a shell and two shock waves, one moving outward and one moving inward. The inward moving shock wave heats the stellar wind to X-ray-emitting temperatures."

NGC6995 Eastern Veil Nebula

 The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus. It is a large supernova remnant which was formed some 5000 to 8000 years ago. The distance from Earth to the nebula is roughly 1500 light years. NGC6995 denotes one of the Eastern parts of this large nebula.

B33 Horsehead Nebula

This famous dark nebula is located in emission nebula IC 434 in the constellation Orion. Distance from earth to Horsehead Nebula is approcimately 1500 light years. Dark dust and gas forms horse-like shadow on emissive hydrogen background. This shape was first noticed by Williamina Fleming in 1888.

Below is my narrowband Ha exposure of  B33 in grayscale palette. This project has just started. More exposure and more channels will be added later. Click for larger image!
