This is Sharpless 2-240, a very faint remnant of a supernova. This nebula is about 100,000 years old. If it was bright enough to see in the night sky, 6 of our moons laid side by side would equal the length of this object.The nebula is about 3000 light years away. This image consists of 350 minutes of hydrogen alpha exposure, and one hour through green and blue filters. Telescope used was a Takahashi FSQ106, the camera was an SBIG STL11000 on a Paramount equatorial platform. This image was taken over 2 nights on January 1-2, 2009.
