Now, he was able to take pictures of the ISS transiting the Sun while two astronauts were doing a spacewalk. As an added challenge, Legault made sure he was in the right place at the right time so he could capture the ISS (and astronauts) while they were passing by three enormous sunspots.
A group of amateur and professional astronomers have collaborated to create what may be the highest resolution global map of Mars ever created with images taken from Earth.
The images were taken with the 1-meter telescope at the Pic-du-Midi observatory in the Pyrenees of France, during several nights in October and November, 2020 when Mars was at opposition, or its closest approach to Earth.
Always on the lookout for interesting events in the skies, astrophotographer Thierry Legault has captured an incredible video of SpaceX’s Dragon capsule traveling through space just 20 minutes after it launched from Kennedy Space Center on June 3, 2017.
“You can see the Dragon, the second stage of the Falcon 9 rocket, and solar panel covers,” Legault told Universe Today via email, “plus a nice surprise I discovered during processing: several fast ejections of material, certainly thrusters firing!”
Legault captured at least 6 ejections of material during the passage over his location in Tours, France. The three brightest are highlighted at the end of this video. He used a Sony Alpha 7S with a 200mm lens.
So, what you’re seeing is the Dragon traveling through the background of stars. Legault hand-tracked the Dragon, so even though it appears as stationary (with a few bumps here and there) and objects are zooming past, the capsule is in fact moving at close to 17,500 mph (28,000 km/h). This was taken a just few minutes after the capsule separated from the Falcon nine upper stage and jettisoned the covers on the solar panels, so all the individual bright ‘dots’ seen here were still near each other, moving together in Earth orbit.
This Dragon is now docked at the International Space Station, as the launch was the CRS-11 (11 of 12 planned Commercial Resupply Services for SpaceX.) This was the first time that a Dragon spacecraft was reused, and it brought supplies and science experiments to the ISS. As SpaceX has now done several times, the first stage booster landed back at KSC. This was also the 100th launch from historic pad 39A. Read more about the launch and mission here.
This isn’t the first time Legault has captured the Dragon in flight; he also shot footage of Dragon on its way to the ISS in April of 2014. Recently, he also was able to take multiple images of the ISS passing in front of the Moon:
Thanks to Thierry for sharing his footage and images with Universe Today. Keep track of his amazing work at his website.
Who doesn’t love to gaze at the Moon on a clear night? But astrophotographer Thierry Legault now taken Moon-gazing to new heights. Legault traveled to the Alps in August and set up his Celestron C14 Edge HD and ZWO ASI1600MM camera. The results are absolutely stunning.
“These are the largest and sharpest quarters ever,” Legault said via email, adding that he created mosaic images of 10 fields for a definition of 150 million pixels!
Above you can see incredible detail in the 58 mile-wide (93 km) impact crater Copernicus.
Below is a lunar quarter taken on August 24, 2016:
In his book, “Astrophotography,” Legault said that for clear close-ups of the Moon, good atmospheric conditions are a must, as well as having a finely tuned or collimated telescope. Below is a close-up view of Triesnecker crater and the surrounding region near the central part of the Moon’s near side, including sharp view of the rilles.
For processing these images Legault used AutoStakkert!2 (AS!2), PTGui stitching software and Photoshop.
You can see more of these stunning shots at Legault’s website, where he says he’ll have posters of these images available soon.
Of course, you can try seeing these features on the Moon yourself. Even binoculars or a small telescope can provide wonderful views of our closest companion in space. An upcoming full Moon (Super Moon!) on November 14, 2016, will feature the closest full Moon (356,509 kilometers away) until November 25, 2034 (356,448 kilometers away.)
Our thanks to Thierry Legault for sharing these wonderful new images of the Moon!
If seeing the Northern or Southern Lights hasn’t been crossed off your bucket list yet, this video is the next best thing to seeing the aurora live. Astrophotographer extraordinaire Thierry Legault has captured spectacular views of the Aurora Borealis from Norway, filmed in real time.
“I was in Norway in early November,” Thierry told Universe Today, “this was my 5th stay and really the best one, with incredible auroras. At moments they were so large and fast that we didn’t know where to look.” He added they were “totally hypnotic.”
The 16-minute video includes 6 of the best sequences Legault captured. “I included the start and finish of the sequences to show their behavior to people who have never witnessed them,” he said. “The auroras seem to be alive, sometimes like snakes or rivers.”
Legault used a Sony Alpha 7s, which he says is the only camera able to record video like this in such lighting. The video is recorded at 25 frames a second.
For the best view of the video, switch to full HD mode (1080p) and full screen.
To our knowledge, this is the first time anyone has ever photographed a transit of the International Space Station of the Moon DURING a lunar eclipse. And guess who did it?
Not surprisingly, it was the legendary astrophotographer Thierry Legault.
Usually, Thierry will travel up to thousands of miles to capture unique events like this, but this time, he only had to go 10 miles!
“Even if I caught a cold, I could not miss it,” Thierry told Universe Today in an email. “The Moon was very low on the horizon, only 16 degrees, so the seeing was not very good, but at least the sky was clear.”
Still, a stunning — and singularly unique — view of the “Super Blood Moon” eclipse!
See the video below:
It was a quick pass, with the ISS transit duration lasting a total of 1.7 seconds. Thierry uses CalSky to calculate where he needs to be to best capture an event like this, then studies maps, and has a radio synchronized watch to know very accurately when the transit event will happen.
“For transits I have to calculate the place, and considering the width of the visibility path is usually between 5-10 kilometers, but I have to be close to the center of this path,” Legault explained, “because if I am at the edge, it is just like an eclipse where the transit is shorter and shorter. And the edge of visibility line of the transit lasts very short. So the precision of where I have to be is within one kilometer.”
Here’s the specs: ISS Speed: 25000 km/h (15500 mph). ISS Distance: 1100 km; Moon distance: 357,000 km (320x).
You can see other imagery from around the world of the lunar eclipse here, with images taken by Universe Today readers and staff.
Universe Today’s David Dickinson said he’s been trying to steer people towards trying to capture an ISS transit during a lunar eclipse for quite some time, and concurred that Thierry’s feat is a first. Dave made a video earlier this year to explain how people might photograph it during the April 2015 lunar eclipse, but unfortunately, no astrophotographers had any luck.
Thanks again to Thierry Legault for sharing his incredible work with Universe Today. Check out his website for additional imagery and information.

When you’re Thierry Legault and you want to challenge yourself, the bar is set pretty high.
“This is a challenge I imagined some time ago,” Legault told Universe Today via email, “but I needed all the right conditions.”
The challenge? Capture a transit of the International Space Station of not just the Sun — which he’s done dozens of times — but in front of a solar prominence.
Legault said the transit of the prominence, which he captured on August 21, 2015, lasted 0.8 seconds. His camera was running at 40 frames per second, and he got about 32 shots in that time.
See a video of the transit in real time, and more, below:
We’ve described in our previous articles how Legault determines the exact location where he needs to be to capture the images he wants by considering the width of the visibility path, and trying to be as close to the center of the path as possible. But this challenge was a bit different.
“I took the last transit data from Calsky, the real position of the prominences, and made angles and distances calculations to place my telescope this time not on the central line of the transit but 1 mile north from it,” Legault said, “to have the ISS passing in front of the largest prominence.”

Cue the “Space Invaders” sound effects! We’ve shared previously how astrophotographer Thierry Legault will travel anywhere to get a unique shot. He took this impressive but fun video of an Iridium 72 satellite flaring and passing in front of Jupiter, traveling to Oostende Beach at the North Sea in Belgium to capture this transit. He took both a wide angle view as well as the telescopic close-up view of Jupiter, and from the vantage point of Earth, it appears as though Jupiter gets blasted by the flare. In the zoomed-in view, even Jupiter’s moons are part of the scene.
You can almost hear the “pew-pew.”
Legault also shared a another recent video he shot of the Chinese Yaogan 6 satellite. “It is probably out of control, quickly tumbling with very bright and short flashes,” Legault said, and it has been tumbling for about a year. Yaogan 6 is a radar reconnaissance satellite launched by China in 2009. Legault said he did the tracking by hand with professional video tripod with a fluid head.

The weather is always fine in Southern Spain…except during eclipse days!” Legault told Universe Today via email. “I had to drive a lot trying to find clear skies, finally the sky was covered with thick high clouds but I got the ISS passing in front of the Moon during the eclipse.”
“Double partial eclipse today!” Legault tweeted. “The Moon and #ISS in front of the Sun, taken from Spain.”
“For transits I have to calculate the place, and considering the width of the visibility path is usually between 5-10 kilometers, but I have to be close to the center of this path,” Legault explained, “because if I am at the edge, it is just like a solar eclipse where the transit is shorter and shorter. And the edge of visibility line of the transit lasts very short. So the precision of where I have to be is within one kilometer.”
Legault studies maps, and has a radio synchronized watch to know very accurately when the transit event will happen.
