Respighi AND NASA -- Ancient Airs and Dances, Suite 2, M. 4
Psychedelic Space Redux
is a composite of a series of images photographed from a mounted camera
on the Earth-orbiting International Space Station, from approximately
240 miles above Earth.

Flight Engineer Don Pettit said of the 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."
A total of 47 images photographed by the astronaut-monitored stationary camera were combined to create this composite.
