The nebula Sharpless 112 lies very close to the star Deneb, just opposite the far more famous North America Nebula. It contains emissions in H-alpha, O-III, and S-II (though the oxygen is rather weak) so it has been rendered here as a narrowband image. Exposure times were H:O:S:R:G:B = 120:90:90:20:20:20, with O-III and S-II binned 2x2. Just above Sharpless 112 in the sky are Sharpless 115 and 116, which you can find elsewhere in this gallery.
