Every 780 days, the Sun, the Earth and Mars are found aligned in this direction.
And this was the case in October, the red planet is said to be in opposition, the occasion for the Pic du Midi to scrutinize it thanks to its telescope one meter in diameter.
So many images that allowed three amateur and professional astronomers to build a complete planisphere, and even a 3D version, where we can see the polar cap of the planet.
“Based on our images of Mars taken over six nights in October and November, Jean-Luc Dauvergne built a complete planisphere and generated hundreds of images to make a rotating globe of Mars.
These two stereo pairs show the rotation in 3D.
We use the parallel technique.
Two rolls of paper or cardboard, held like binoculars, can help direct each eye towards the corresponding globe ”, explains on social networks Thierry Legault, specialist in astrophotography.
March on Oct 30th from the Pic-du-Midi observatory, taken by François Colas and I using the 1-meter telescope, processed by Jean-Luc Dauvergne.
Not a "great Pic" night but we had a fair window of seeing during 40 minutes.

A complete mapping of Mars
Images taken with François Colas from the Institute of Celestial Mechanics and Ephemeris Calculation and staged, after several hours of work, in a rotating and 3D version by Jean Luc Dauvergne of Ciel et Espace.
On arrival, this gives a complete cartography of Mars with an almost unmatched resolution for images taken from the cow floor.
