the spectacular image of the station taken with a 30,000 euro telescope

An expert in astrophotography had been chasing a very special photo for some time: that of the International Space Station (ISS) in its transit over the Moon.

Last January Thierry Legault achieved that photo. He had to travel 250 km and cross his fingers that the fog would allow him to capture her, but the result is really spectacularespecially considering that the ISS moves at 27,000 km/h and is located at an altitude of 450 km.

His tool is a 30,000 euro telescope

Legault, an engineer and astrophotography enthusiast — there are amazing photos of people like him — searched for the perfect location for the photo. He lives in Paris, where light pollution would make something like this very difficultso for this photo he made a trip to rural Bourges.

The night was complicated by the presence of fog, but fortunately this dissipated when Legault needed it: just at the moment when the transit of the ISS over the Moon could be photographed.

Those calculations can be done easily thanks to the website ISS Transit Finder with which the Space Station can be tracked, and from there it only remained to place all the equipment and establish the appropriate parameters for that photo. There are other tools to be able to check that position of the ISSWhat Spot The Stationfrom NASA.

in the end it’s over taking about 400 frames with an exclusive telescope from the manufacturer CFF, specifically the ZWO ASI183 Refractor with 200 mm aperture. The instrument is not cheap at all: around 30,000 euros according to the model.

For that unique “burst” of photos, he made use of an exposure time of 1/6000 secondsa key and necessary parameter to capture the International Space Station as clearly as possible, especially considering that it moves at 27,000 km/h.

Legault, who has already written three books on astrophotography and regularly publishes articles on his work, had already captured transits of the ISS over the Moon and over the Sunbut this is according to him his best photo of this unique event.
