ISS Star Trails – langzeitbelichtete Bilder von der ISS

0

Diese atemberaubenden Aufnahmen mit Langzeitbelichtung machte Astronaut in Ingenieur Don Pettit bei seinem Aufenthalt auf der ISS:

Expedition 31 Flight Engineer Don Pettit relayed some information about photographic techniques used to achieve the images: “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.”
