I am engineer and I live in the suburbs of Paris (close to Versailles), in a site that is very polluted by city lights. From my backyard, I can take images of the Sun, the Moon, planets and nebulas with narrow band filters. For deep sky imaging (galaxies, comets, nebulas...), I am obliged to go in the land, after loading my van. I began digital imaging (CCD) in 1994.
The asteroid number19458 has been officially named Legault at the International Astronomical Union.
I have written two books: The New Atlas of the Moon with Serge Brunier (Firefly) and Astrophotographie (Eyrolles).
I have written numerous articles and lectures about imaging in Europe and USA (Sky and Telescope, Ciel et Espace, Astronomie Magazine, Chasseur d'Images...).
My photographs, especially of space shuttle and space station, have been published in newspapers and magazines and have been shown on TV worldwide: The Times, The Guardian, The Daily Mail, The Wall Street Journal, CNN, Fox News, ABC News, CBS News, Discovery Channel, Science et Vie, le Monde, le Figaro, le Point, Ca m'Intéresse, TF1, France2, M6...
I have made several photo exhibitions and given many lectures during: NEAF (New-York) in 2008 and 2011, RCE (Paris) in 2006, 2008 and 2010, AIP workshops in 2008 and 2010, Festival de Photo de Nature de Montier-en-Der in 2008, Salon de la Photo (Paris) in 2007 and amateurs meetings in France, Germany, Netherlands, Bergium and Greece between 2004 and 2010.
