An amazing new photograph shows the International Space Station (ISS) crossing in front of the bright and seemingly enormous moon.
We're used to seeing images taken from the space station — astronauts often post them on social media — but photos of the orbiting lab from Earth are rarer and take much more preparation.
Amateur astrophotographer Dylan O'Donnell took the stunning photo on June 30 from Byron Bay in New South Wales, Australia, using a Canon 70D camera attached to the rear cell of a Celestron 9.25-inch (235 centimeters) telescope.
O'Donnell received an alert for the precise to-the-second timing of the space station's flyover online. He'd been waiting for a year for such an opportunity, O'Donnell wrote on his website.
"If you think that it might be a case of sitting there with your camera and a clock, with one hand on the shutter release, you’d be absolutely correct!" O'Donnell wrote. "The ISS only passed over the moon for 0.33 seconds as it shoots by quite quickly. Knowing the second it would pass, I fired a 'burst' mode of exposures, then crossed my fingers and hoped it would show up in review — and it did!
O'Donnell was able to sharpen the image of the moon and enhance its colors to depict its complexity and texture by combining those images using astrophotography software with ones he took of the moon just before and after the transit.
He used the website Calsky.com to pinpoint the flyover's timing — a strategy that other astrophotographers have found success with in the past. (This spectacular composite photo of the ISS crossing the sun's face is one example.)
O'Donnell's photo has made quite a splash, appearing on a number of news sites and even being featured on The Weather Channel — all because one photographer was prepared with a camera setup and knew what to look for.
