Fire and ice in the claw of the Scorpion: Sh2-1 with Pi Scorpii and LBN 1093

Rho Ophiuchi and the Blue Horsehead get all the attention (and for good reason), but Scorpius has some additional less-visited regions that are really quite striking.  This image is mostly made up of unfiltered OSC data, but I also used my monochrome camera to capture some additional RGB, luminance, and Ha frames to give it a bit more punch.
