By no means do we want to be conspiracy theorists here on the site, but when you see incredible photographs by astronauts in space, in this case Don Pettit and his recent shots of star trails aboard the International Space Station, do you ever wonder if all space photos are just really incredible photoshop jobs and staged? Like the famous photo of Buzz Aldrin on the moon? Neil was that good of a photographer? Just saying. Anyway, these are just too amazing to be real...
In Don's words, “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, the ‘stack’ them using imaging software, thus producing the longer exposure.”
