Finnish photographer spent 12 years and 1250 exposure hours creating a mosaic photo of the Milky Way. (3 photos)

Modern space observatoriesprovide humanity with a huge photographic material for studying the Universe using sophisticated high-tech equipment. Professional photographer from Finland J.P. Metsavainio has attempted to create a giant photographic canvas of a portion of the Milky Way using standard optics, the PhotoShop software, and the results of 12 years of continuous work.

A huge section of our Galaxy photographerpresented in the form of a mosaic canvas composed of 234 individual elements combined into a single photograph with a width of 100,000 pixels and a resolution of 1.7 Gigapixels. The enthusiast collected mosaic elements for 12 years from 2009 to 2021, spending 1250 hours on filming. The photograph captures a sector of the Milky Way with an angular size of 125 by 22 degrees and shows over 20 million stars and constellations.

On the process of working on a giant mosaicMetsavainio tells on his website, where you can see both the general canvas of 7000 x 1300 pixels, and individual elements of the picture, which in themselves are a magnificent visualization of a part of the vast Universe. In the first stage, the photographer took pictures of the most spectacular and beautiful regions of the Milky Way. Noticing that on the basis of long-term work it is possible to compose a single photograph, the enthusiast began to specially photograph the missing parts of the sky, filling in the "white spots" on his mosaic.

At the final stage, he "sewed" separatephotographs using the brightest and most famous stars as control points and obtained a general image using standard PhotoShop. The panorama shows photographs of areas of gas systems reflecting light with ionized elements: hydrogen in green, sulfur in red and oxygen in blue.
