|"Double, double toil and trouble..." Alas, had MacBeth seen
this nebula in the sky his portentous future would have been
as obvious to him as it was to the witches that begin Shakespeare's
play. Not unlike the foul vapors that curl from the witches cauldron,
IC2118 wafts through space at a nearby 1000 light years away. The star Rigel,
Orion's luminous limb, lights up this nebula blue both by its own
color and scattered light in the dust of this nebula. Hints of red also permeate the
field showing that some of the gas is excited by the starlight. The glow
of light towards the bottom of the field is an artifact caused by the scattered
light of Cursa, a seemingly appropriate name for a star near the "WitchHead"
nebula. (Actually, from the Arabic Cursa is related to a footstool of Orion)
