This is an older image I took in the summer of 2010. It is about 45 minutes of data at ISO 800.
From APOD:
Wisps like this are all that remain visible of a Milky Way star. About 7,500 years ago that star exploded in a supernova leaving the Veil Nebula, also known as the Cygnus Loop (of which the above image is only of the eastern half). At the time, the expanding cloud was likely as bright as a crescent Moon, remaining visible for weeks to people living at the dawn of recorded history. Today, the resulting supernova remnant has faded and is now visible only through a small telescope directed toward the constellation of the Swan (Cygnus). The remaining Veil Nebula is physically huge, however, and even though it lies about 1,400 light-years distant, it covers over five times the size of the full Moon.
I just love the simplicity of this photo I shot the other day. There were dragonflies all over the lily ponds at the Biltmore, but unless they're at rest, those suckers are hard to keep up with!
