Back in 2009, Metsavainio began this project, which is a 100,000-pixel mosaic of the Milky Way composed of 234 individual images all stitched together. The resulting image captures the entire galaxy, speckled with about 20 million of the Milky Way’s roughly 200 billion stars.
So, how could a single image take 12 years?
In his blog, Metsavainio points to “the size of the mosaic and the fact that the image is very deep. Another reason is that I have shot most of the mosaic frames as individual compositions and published them as independent artworks.” In the blog, Metsavainio also includes information about the different cameras and some of the more specific techniques he used to create this image.

For example, a single supernova remnant took over 60 exposure hours, he explains in his blog.

These pieces of the full picture showcase the beauty of celestial objects like the California Nebula, the Pelican Nebula, the Wizard Nebula and more.
