Certainly one of the
most dramatic and busy areas of Orion, this image has Zeta and
Epsilon - the left two belt stars in this field. The framing
here was very thought out and deliberate. Just to right of center
is NGC1990 the main focus of this image. This mountainous looking
mix of emission and reflection neblosities overlays a huge red
arc of hydrogen. It forms a dramatic U shaped reflection nebula
that arcs downwards to the right and back up terminating at IC423
the "Teardrop" Nebula. Note that this object is rimmed
in red as well. See how the reds change at top from deep crimson
to the lower left an intense pink from the additional h-beta
line as Zeta adds its emission to the mix. Finally, for perspective
on where this field is located, Ive put the Horse Head nebula
in the lower left corner which also gives an overall scale to
the image.
