The Lagoon Nebula, M8, in the light of Hydrogen Alpha
A deep look at the Lagoon Nebula in the light of Ha, taking advantage of the very high contrast that narrowband filter imaging provides. The dynamic range has been compressed substantially to bring out the faint outlying nebulosity, the detailed structures within the nebula and the numerous dark "Bok Globules", regions where stars are currently being formed. Distance 4100 ly.
