Witch Head Nebula
is a reflection nebula, illuminated by the bright star Rigel, not seen
on the image but off to the right. Rigel is the bottom-right
star of the constellation Orion. The
Witch Head is located 900 light-years from us, and is quite possibly a
super nova remnant. North is at the bottom.
