This website is mainly dedicated to astronomy, covering the solar and planetary observations to the deep-sky photography.
There are also some sections treating some effects linked to the Earth atmosphere, like lightnings and rainbows. All pictures have been taken by the author.
In the case of download and further use, please simply mention the source. This page is temporarily devoted to the comet C/2020 F3 (Neowise),
which was the astronomical surprize of the summer 2020, and to the famous solar eclipse of August 21, 2017.
