What the Hell is That - The Rarely Photographed Sh2-260

This very faint filamentary region in Orion is rarely photographed. I can find no great explanation of exactly what it is or why it’s there. So it makes me ask the question:

Classified as an hydrogen emission region (an area of ionized hydrogen—essentially free-floating protons and electrons), scientists don’t know what caused the filamentary structure, but they think it might be connected to the nearby molecular cloud in Orion.

Several prior imagers have noted that there’s little or no oxygen signal in the area. I can confirm that, although I did pick up a few very faint filaments in the oxygen band. What surprised me, however, was the strength of the sulfur signal in the sulfur band. Because of the very weak oxygen signal and the strong sulfur signal, I processed this image using an HoSS palette (hydrogen plus some oxygen as red, and sulfur assigned to both green and blue). The result is a baby only a mother could love. But I felt that because this area is so rarely photographed, it needed to be seen.
