photo 14 May 175 notes the-star-stuff: Is This the Trippiest Image Ever Taken In Space? Most Probably The image was made by Expedition 31 Flight Engineer Don Pettit, who composited it from 18 different shots: 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.

    Moden digital cameras can take exposures much longer than 30 seconds. Get your facts straight.
