An experimental M8, the "Lagoon nebula"
M8 in HST-palette, 50% broad band luminance used at top of the NB image, 100% for the Stars.
M8 in natural color narrow band composition, 50% broad band luminance used at top of the NB image, 100% for the Stars.
Original pure narrow band compositions can be found here:
Technical details are behind the link above.
Star colors are not RGB-colors!
They are mixed from O-III and H-alpha stars by using a scientifically "wrong" method as a form of artificial Green channel.
Luminance information, 7x300s, dark calibrated.

M8, the "Lagoon nebula"
HST-palette from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen
This composition is very close to a visual spectrum.

Edit 05.06.2010
Here is a Starless version of M8, I like to do some tricks with the images and the results are experimental in nature. Actual nebula can be seen better here.
