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 HII 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 OIII band. What surprised me, however, was the strength of the sulfur signal in the SII band. Because of the very weak OIII signal and the strong SII signal, I processed this image using an HoSS palette (HII plus some OIII as red, and SII 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.
