This photograph was taken by the Canada-France-Hawaii telescope that sits
on top of Mauna Kea, Hawaii. The dark molecular cloud, roughly 1,500 light years
distant, is cataloged as Barnard 33 and is visible only because its obscuring
dust is silhouetted against the bright emission nebula IC 434. The bright blue
reflection nebula NGC 2023 is visible on the lower left. The prominent horse
head portion of the nebula is really just part of a larger cloud of dust which
can be seen extending toward the bottom of the picture.
