Thierry Legault’s Incredible Ground-Based Views of Endeavour’s Final Flight

[/caption]

Award-winning French astrophotographer Thierry Legault traveled through Germany, France and Spain during Endeavour’s final mission to find clear skies and good seeing to capture the shuttle’s voyage to the International Space Station. While he told us it wasn’t easy, the results are incredible! The visible detail of the shuttle and parts of the International Space Stations is absolutely amazing. You can see the newly installed Alpha Magnetic Spectrometer in one shot, as well as the open payload bay doors on Endeavour in another. The video Legault shot is available on his website, and he has unique 3-D versions as well.

Below are some of his trademark views of transits of the Sun by ISS and Endeavour, with one showing the shuttle just before it docked to the station.

Legault told us he was chasing the shuttle and the station from different parts of Europe, however because of weather problems (clouds and turbulence) he was not very happy with the results. But this image is stunning anyway even though clouds dimmed available light by more than 100 times, Legault said. What is perhaps most amazing is that the transit time for this pass in front of the Sun was 0.7 seconds!

Here’s a less cloudy view taken on May 25:

And the full view for reference. This transit was only a half second!

All transit images were taken with Takahashi TOA-150 6″ apochromatic refractor (focal length 2400mm and 3600mm) on EM-400 mount, Baader Herschel wedge. Nikon D3X at 1/8000s, 100 ISO, working in continuous shooting at 5 frames per second during 5 seconds.

Here are frames from videos taken by Legault and fellow astrophotographer Emmanual Rietsch just prior to the deorbit burn for landing on June 1. The video of these shots, as well as more images are also available on Legault’s website.

Thanks to Thierry for sending Universe Today these amazing images and allowing us to post them!
