Lagoon Nebula – M8

Lagoon Nebula

Lagoon Nebula

A mere 4,000-6,000 light years away, the Lagoon Nebula contains many Bok globules (dark collapsing clouds). At the nebulas center is a structure known as the Hourglass Nebula named by John Herschel, which provides direct evidence of active star formation.

Photographed in LRGB and Hydrogen-Alpha, this target never exceeded 27 degrees on the horizon, thus making it a difficult subject to be photographed from Colorado.
