Ma contribution en lumi\u00e8re Blanche.
\nLunette achromatique TS 152mm f\/5.9 +
\nPrism de Herschel Baader +
\nFiltre Solar continuum 540 nm +
\nFiltre densit\u00e9 neutre 0.6 & 0.9 +
\nPowermate TV x 2 +
\nCamera 1\/1,8″AVT Manta 282B ICX687
\nStack avec Autostakert de 100 images issues d’un film de 914 images prises en 30 secondes.
\nJe pense que le flou qui entoure Mercure est li\u00e9 au mouvement de la plan\u00e8te pendant la dur\u00e9e du film.
\nDiam\u00e8tre de Mercure 4879 km
\nDiam\u00e8tre d’une cellule de convection solaire (granule) 1000 km.
\nCQFD.
