Incredible long exposures shot by astronaut Don Pettit, currently orbiting earth aboard the International Space Station.
Currently on board the International Space Station is an astronaut with a very keen eye for photography – Don Pettit. Don’s been shooting some amazing long exposures from orbit during his expedition.
“My star trail images are made by taking a time exposure of about 10 to 15 minutes. However, with modern digital cameras, 30 seconds is about the longest exposure possible, due to electronic detector noise effectively snowing out the image. To achieve the longer exposures I do what many amateur astronomers do. I take multiple 30-second exposures, then ‘stack’ them using imaging software, thus producing the longer exposure.”
We’re not sure what he means with the “electronic detector noise”, as modern CMOS sensors can easily record longer exposures, but this could have something to do with shooting in space. View more photos over at NASA’s Flickr set.
