2014-06-22 * The Veil Nebula in the constellation Cygnus (combined 36-minute exposure)
** NOTE: The bloating of the star images in this image was caused by some dew that was on the lens during the half hour required to make the exposures. This doesn't make me happy.

Per Wikipedia: The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus. It constitutes the visible portions of the Cygnus Loop, a large but relatively faint supernova remnant. The source supernova exploded some 5,000 to 8,000 years ago, and the remnants have since expanded to cover an area several times as large as the apparent diameter of the Moon. The distance to the nebula may be about about 1,470 light-years.
Nikkor 80-400 mm lens on Nikon D800 camera body (modified, red blocking filter removed), at 400 mm; ISO 2500 at f/7.1.
Six 6-minute exposures, stacked in Registar and processed in Photoshop CS6
