This is Pickering's Triangle, well a small part of it. Turns out to be way too big for my system. So I never took any color data. It is way too faint to take without using H-alpha filters which I didn't do, unfortunately. This made me dig into the noise to get what I did get. That is not easy due to the flat problem I was having at the time due to a loose screw in the camera preventing filters from aligning properly each time, so I cropped and reduced the image to hide problems with the flats. Still, it is an interesting picture. This is part of the Cygnus loop complex which covers an area of the sky 6 full moons across so way too big for my system. I can't even fit one full moon into my field of view, let alone 6 of them. The nebula is formed by the interaction of the shock wave from the supernova hitting interstellar gasses. At one time it was thought the supernova blew about 100,000 years ago but of late it is thought to be much newer. Most now think it happened 10,000 or less years ago. We've never found the neutron star or black hole that was created by the explosion. The shock wave is the only evidence of the explosion.
