NGC7000 - The Wall
The prominent ridge of emission featured in this image is known as the Cygnus Wall. Part of a larger emission nebula with a distinctive shape popularly called The North America Nebula, the ridge spans about 10 light-years along an outline that suggests the western coast of Mexico. Constructed from narrowband image data, the cosmic close-up maps emission from sulfur, hydrogen, and oxygen atoms to red, green, and blue colors. The result highlights the bright ionization front with fine details of dark, dusty forms in silhouette. Sculpted by energetic radiation from the region's young, hot, massive stars, the dark shapes inhabiting the view are clouds of cool gas and dust with stars likely forming within. The North America Nebula itself, NGC 7000, is about 1,500 light-years away. (Text from NASA APOD).

Not posted any images for a while as I have been building a new homemade observatory so I can now leave the scope permanently mounted on the roof. Hope to post some more details of that soon. This is the first image taken from it. Hopefully many more to come!
