The War and Peace Nebula, also known as NGC 6357, is a vast emission nebula located in the constellation Scorpius.

It is a site of active star formation, and the region is home to numerous hot, young stars. The nebula's distinctive shape is believed to be the result of intense radiation and stellar winds from these massive stars, which have sculpted the surrounding gas and dust into complex patterns.

The name colloquial name "War and Peace" was chosen by a team of scientists which saw structures which resembled both a skull and a dove on different regions of the nebula. It is also referred to as the "Lobster Nebula".

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.
