Henize 70, also known as N70, is a large and complex superbubble located in the constellation Dorado, approximately 170,000 light-years away from Earth.
It was formed by multiple supernova explosions that occurred in the region, creating a vast and fascinating structure that spans over 300 light-years across.
The superbubble is surrounded by filaments of ionized gas, which are illuminated by the hot, young stars that lie at its center generating complex ripples and patterns.
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.
