Stardust of the Lagoon Nebula (Messier 8)
Data captured earlier this year, only processed now as the cloudy weather starts. Experimenting with a different processing technique, and highlighting the dust clouds (consisting mainly of Hydrogen), with star reduction so that the gas and dust stand out.
The Lagoon Nebula (M8, Messier 8 or NGC 6523), is a giant interstellar cloud in the constellation Sagittarius. M8 is estimated to be between 4,000 - 6,000 light-years from Earth in the Milky Way Galaxy, and is classified as an emission nebula.
About Emission nebulae:
Emission nebulae are glowing clouds of interstellar gas which have been excited by some nearby energy source, usually a very hot star. The red light seen in this picture is glowing hydrogen captured in the Hydrogen-Alpha (Hα) Infrared wavelength of light at 656nm.
