The Eastern Veil Nebula

The Veil Nebula: Eastern Veil Section also known as Caldwell 33 - containing NGC6992 and NGC6995 and the Southeastern Knot. Taken from our backyard in the early morning of the 24th September 2016. 127mm Meade Apo-refractor - 0.8x focal reducer and field flattener - Canon 600D DSLR- guided with a QHY5-11 guide camera. 36 minutes total exposure in 12x3 minute subs.

 Very pleased with my image ("thinks a lot of himself") as the nebula radiates most of its light at the wavelength of doubly ionized oxygen - 500.7 nano metres and I do not have any specialised filters to enhance emissions at this wavelength. 

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 (radio source W78, or Sharpless 103), a large but relatively faint supernova remnant. The source supernova exploded circa 3,000 BC to 6,000 BC, and the remnants have since expanded to cover an area roughly 3 degrees in diameter (about 6 times the diameter, or 36 times the area, of the full moon). The distance to the nebula is not precisely known, but Far Ultraviolet Spectroscopic Explorer (FUSE) data supports a distance of about 1,470 light-years
The Hubble Space Telescope captured several images of the nebula. The analysis of the emissions from the nebula indicate the presence of oxygen, sulphur, and hydrogen. This is also one of the largest, brightest features in the x-ray sky. Credit: Wikipedia

 Quite something to consider that one of our distant ancestors, one of the first British farmers in the Stone Age, may have looked up and seen a new bright star in the sky, a shining supernova, the wispy remnants of which, at least 5 millenia later, I imaged from our backyard?
