This is NGC 6960, the Western portion of the Veil Nebula, also known as "the Witch's Broom." The Veil Nebula is a cloud of heated ionized gas and dust in the constellation Cygnus. It constitutes the visible portions of the Cygnus Loop, a supernova remnant, the source of which was a star 20 times more massive than the Sun, that exploded between 10,000 and 20,000 years ago. The remnants have since expanded to cover an area of the sky roughly 6 times the diameter, and 36 times the area, of the full Moon. It has been measured at a distance of 2400 light-years from Earth, and its component parts are expanding at a rate of about 1.5 million kilometers per hour. The image, from last night's observing session in Julian, consists of 40 two-minute sub-images taken through a 72 mm refracting telescope and stacked and processed with software.
