The Lagoon Nebula, also known as Messier 8 or M8, is a vast and luminous emission nebula located in the constellation Sagittarius, approximately 5,000 light-years away from Earth.
Its name comes from the dark lane of dust that appears to divide the nebula into two distinct sections.
The Lagoon Nebula is an active region of star formation, with many hot, young stars embedded within its glowing clouds of gas and dust, which makes it an ideal target for astronomers to study the process of star formation.
About the Deep Space Collection:
Shot entirely with my rooftop telescope from the urban skies of Buenos Aires, the Deep Space Collection features many objects observable only from the southern hemisphere.
All images in the collection were shot using individual narrowband filters which cut off most of the light and allow only very specific wavelengths to pass (the light emitted from ionized hydrogen, oxygen and sulfur), making it possible to photograph deep space objects even from the highly light polluted skies of the city.
The images from each separate filter are then processed individually, combined and mapped to RGB channels for a final color image.
Two different color mapping palettes were used in this collection: SHO, where sulfur is mapped to red, hydrogen to green and oxygen to blue in what is referred to as "Hubble Palette" processing (as used in the images the famous space telescope) and HOO, where hydrogen is mapped to red, and oxygen to blue and green.
