Ciel Austral is a team of five enthusiastic French amateur astronomers, Jean Claude Canonne, Philippe Bernhard, Didier Chaplain, Nicolas Outters and Laurent Bourgon, who own and operate their own telescope in northern Chile. The 14400 × 14200 images were assembled from nearly 4,000 separate images, which required 1,060 hours (6.3 weeks) of views taken between July 2017 and January 2019. It took eight days for two computers to assemble the photos and two more months to process them. the 620 gigabytes of data.
If you could point to the Magellanic cloud, it would not look like the dream and pictorial image shown above. Much of the image is composed of false colors that show the different elements present in the image. Different colors represent hydrogen, sulfur and oxygen III, highlighting the cloud – shaped high density gas nebulae in a way that would not be with a standard visible light image.
The image shows the birth and death of stars and their consequences, including supernova remnants, planetary nebulae, and warm, white star-forming regions. In addition to the enhanced color version that uses filters to scan for dust and gases, Ciel Austral has also released a narrow-band image (located below the main image) that gives a better idea of how the galaxy would look in the visible light. Spoiler: It's always beautiful.
