The Witch Head Nebula in Eridanus - IC2118
Imaged from Nova Scotia, Winter 2014
Taken from a bitterly cold, northern winter sky, here she is at the foot of The Hunter, mouth agape, basking in the chilling, blue light of the mighty supergiant star Rigel.
Depicted without stars, the dust and gas comprising The Witch Head, become better defined.

Although very faint, and quite invisible to the eye, she's actually a very large lady on the night sky! Here she is, with the moon at proper scale artificially superimposed with her just for comparison. Incidentally, at a distance of approximately one thousand light years, The Witch is about twenty-four MILLION times further away than the moon!
