The Zeta Ophiuchi Nebula - Sharpless 2-27
Emission and Dark nebula in Ophiuchus
Uploaded 6/12/26

Sharpless 2-27 surrounding the bright blue star Zeta Ophiuchi is an enourmous object, spanning well over 12 degrees in size. Inside we find some gorgeous glowing wisps of deep red, a long snake like dark nebula (LDN204, 234) reffered to as the "Dark Seahorse" nebula. In the very center is a peculiar bluish-white wisp of glowing highly excited oxygen forming a bowshock around Zeta. Notice how the color of this huge nebula changes from top to bottom - deep reds to pinks to magenta. What an incredible field!
