Alexis Tranchandon

Alexis Tranchandon is a music teacher and lives near Paris, France. He discovered the night sky by sailing boats and developed a passionate interest for the cosmos and space exploration, especially for unmanned spacecraft.

He was particularly taken by the quality of reprocessed images from Voyagers missions made by amateurs. He realised that the space imagery databases are absolute treasures opened to all, but was also frustrated to know that many more unprocessed images are likely to stay in that state. He decided to teach himself how to process these images. His work can be viewed on his Flickr page.
