Sh2-273: Fox Fur Shawl or Wrinkled Fleece Blanket?

The Fox Fur Nebula is much fainter than the Rosette (to which it is attached as part of the greater Monoceros Loop), but it has its own beauty. The SII signal occurs in the same regions as H-alpha (typical of HII regions), but the diffuse OIII around the core provides wonderful color contrast in SHO images like this one.

The Sh2-273 catalog entry covers the Cone and Fox Fur Nebulae area in general. Thankfully, we don’t make shawls out of Fox Fur anymore, so let’s say that the area looks like a wrinkled fleece blanket instead. The Christmas Tree Cluster at the center is NGC2264.
