Which is to say, visually, that we have a very terrestrial understanding of nature.

J-P Metsävainio is a nature photographer too, he says. But he doesn't take pictures of our planet or the life on it. He takes pictures of the night skies. "The night sky is part of our nature and the astronomical imaging is a form of nature photography," he wrote to me. Metsävainio lives in the north of Finland, at 65 degrees Latitude.

With his Meade LX200 GPS 12" telescope and some second-hand camera lenses, he captures emission nebulae from within our galaxy, the Milky Way. Each image takes around 10 to 20 hours of exposure. To counteract the natural rotation of Earth (which would result in all stars appearing as streaky arches), he sets his camera on a special mount that rotates in the opposite direction. Each image is composed of multiple sub-exposures of about 20 minutes, sometimes collected over not just days but weeks or even years. The colors in his pictures come from shooting the same object three times through different color filters, similar to the technique of early color photography. "Visually," he explains, "no colors can be detected, even with a large telescope, they are way too dim for human eye."
