Photograph Information:

The Cygnus Star Cloud is a portion of the Milky Way which divides south of Deneb (Alpha Cygni ) and continues south to constellation Ophiuchus. When watching this area you can see the Milky Way to divided into two parts because of the lane of dust which absorbs a good deal of the starlight

The white star on the upper left of the photo is the alpha Cyg  that makes the tail of the swan. It is a super giant about 100 times the diameter of our Sun  and left to it lies a red emission nebula the famous Norh America Nebula ,NGC 7000. Although it is quite large, it is a difficult object to observe because of its low surface brightness. In a clear and dark night one may be lucky to see it with binoculars is called "North American Nebula" because of its shape.

 Close to NGC 7000 and just right to it lies the Pelican Nebula, I5070. This nebula and its neighbor,I5067, are extremely faint for telescopic observations. The two emission nebula are located about 1500 light years away and are separated by a dark absorption cloud. It is still unknown which star or stars ionize the red-glowing hydrogen gas.

The yellow star in the middle of photo is the Gamma Cygni around of which there is a vast region of exceptional beauty of Star cloud and nebulosity in the heavens.
