Shot as a 2x2 mosaic, this image displays a segment of the Large Magellanic Cloud, a satellite galaxy of the Milky Way, situated about 170,000 light-years away.
The image exhibits two remarkable regions of the Large Magellanic Cloud: the Tarantula Nebula and the Cosmic Reef. The Tarantula Nebula is a vast and active star-forming area, spanning over 1,000 light-years, containing thousands of young stars.
The Cosmic Reef is a complex structure of gas and dust molded by the powerful radiation and winds of the stars in the nebula.
Objects within the LMC are some of the very few examples of extragalactic nebulae we can actually observe in detail.
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.
