ISS Star Trails
Posted by Jon M
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.”

OWEN & JAKUB: I propose we come up with a Kickstarter to send all ISO50 Contributors to space.

How might an guy like me become an ISO50 contributor? … before that Kickstarter becomes a reality, of course.

Well done…again. Jonathan, What motivated you to call this blog “ISS Star Trails”, not that the title does not go with the content, I am just wondering. Congratulations again on a good job Jonathan.
