NGC 6960 The Veil Nebula

 

NGC 6960 The Veil Nebula is a cloud of heated and ionized gas and dust, 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 roughly 3 degrees in diameter (about 6 times the diameter of the full moon). The distance to the veil nebula is about 1,470 light years from earth, and this section of the Veil is about 40 light years long. This image is about 1/3 of the Western section of the veil supernova remnant.

Because of the size of the Veil Nebula, and unknown until recently, it was given different NGC numbers. The most prominent is the eastern portion, which is catalogued as NGC 6992. This can be seen in binoculars from a dark site as a long, curving hazy streak of light. The next most prominent part is NGC 6960, as imaged here, lying to the west, which includes the magnitude 4 star designated as 52 Cygni. NGC 6960 can be observed in a 6-inch telescope under dark skies as a faint haze. Other major portions are NGC 6979, the northern part of which is a fainter extension is known as NGC 6974, and 6995, which has an appendix to the southwest called IC 1340. Still other faint luminous material can be found throughout the Veil's expanse.

The dust trails shown, in mostly blue and red, in this image are heightened by the use of Hydrogen Alpha and Oxygen III filters, the nebula is mostly made up of these two elements Hydrogen and Oxygen.

I hope to do a large mosaic of the entire Veil, but it is almost too late in this season to accomplish such an endeavor.
