The inventor of the Zero G Coffee Cup, Don Pettit uploaded some out of this world (couldn’t resist) photography to his Flickr account earlier this year and I only just caught them now. He’s a pretty talented individual who even experimented with a Zero G Electric Didgeridoo.

“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.” Don Pettit

Beautiful.

There have been other projects like this over the years but the execution of this project is spot on! You can also view the rest of her project over on her Flickr account.
