Taken during a waxing gibbous moon.

Over 5 hours of Hydrogen Alpha data on the huge NGC 7000/IC 5070 Nebula complex in Northern Cygnus.

This area is a vast collection of dust and gas in the Orion arm of the Milky way at a distance of about 2000 light years, spanning 100 light years. This group of nebulae, both bright and dark, contains no less than 30 seperate objects, as can be seen in the field of view of the Canon 200mm lens in Cartes du Ciel.
