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.
Less compressed images here:
-
M8, the "Lagoon nebula" in Constellation Sagittarius.
Image field is about 30' x 30', half a degrees.
A new project, from Northern galactic remote telescope in Australia.
The Lagoon nebula, M8, in ionized light from the Three elements, H-alpha, O-III and S-II.
100% crop from the image of M8
The telescope and technical information:
16" RCOS ja Apogee U9000 camera.
LRGB combo.
H-alpha 4x1200s, Dark and Flat calibrated.
O-III x1200s, Dark calibrated
O-III x1200s, Dark calibrated
Raw data is shared with Petri Kehusmaa and J-P Metsavainio
Processing workflow:
Image acquisition, MaxiDL v4.xxx
Stacked and calibrated in CCDStack.
Deconvolution with a CCDSharp, 30 iterations
Levels, curves and color combine in PS CS3.

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.
