This is a cloud of glowing Hydrogen gas about 65LY across, located up and left from Orion about 5000LY away.

This image was 7 x 600sec subs taken with a modified Canon 1000d through an Astronomik CLS CCD filter using a William Optic FLT98 Triplet refractor at f5. The scope was mounted on a guided NEQ6 GEM mount and the image was stacked and processed in Pixinsight then tweeked in PS CS5.
