Full Moon by Bartosz Wojczyński

When viewed with the naked eye, the moon appears to be a colorless object. It turns out, however, that with the use of specialized photographic techniques, we are able to “extract” a lot of color details from the surface of our satellite.

The picture was taken with a 2.4 meter focal length telescope. The image was recorded with a dedicated monochrome camera for astrophotography equipped with red and blue filters.

By increasing the differences between the color channels of the image many times over, we get an image that clearly shows very subtle differences in the color of the Moon’s surface. Orange areas show more iron oxides, while blue areas show titanium oxides.

Perfect for astronomy aficionados, educators, or anyone captivated by the night sky, this poster serves not only as an impressive decorative piece but also as an inspiring educational tool, fostering curiosity about celestial mechanics and space exploration.
