Bonjour,
\nde retour de l’ile de Kirk (prononcez Keurk) en Croatie, je vous pr\u00e9sente un petit croa du transit de Venus photographi\u00e9 en compagnie de Marc Tannier depuis le parking jouxtant la baie de Saint Marak \u00e0 Risika. Notre position Google \u00e9tait 45\u00b006′ 21 N et 14\u00b039′ 55 E de sorte que nous pouvions voir le soleil appara\u00eetre au dessus des collines du continent peu apr\u00e8s son lever. Petite peur, le ciel \u00e9tait pratiquement serein \u00e0 l’exception d’un nuage qui d\u00e9filait au NE, juste pr\u00e8s de la zone o\u00f9 devait se lever le soleil mais tout s’est finalement bien pass\u00e9.
\nToutes les photos sont prises au Canon 350d plac\u00e9 au foyer de la lunette Televue NP101IS (101mm de diam\u00e8tre pour 540mm de focale). Les couleurs des diff\u00e9rentes images n’ont pas \u00e9t\u00e9 modifi\u00e9es et sont dues au filtre Astrosolar Baader qui a servi \u00e0 att\u00e9nuer la luminosit\u00e9 du soleil. Pour chaque vue, je donne le temps de pose, la sensibilit\u00e9 et l’heure belge de la prise de vue.
\nNotez enfin que les trois derni\u00e8res images de la s\u00e9quence sont prises \u00e0 travers un voile de cirrus de plus en plus \u00e9pais.<\/p>\n

image 1: test de map du 5juin. 1\/1600\u00e8 100iso 19hr04<\/p>\n

image 2: peu apr\u00e8s l’apparition du soleil au dessus des collines. 5sec 400iso 05hr37<\/p>\n

\"\"<\/a><\/p>\n

image 3: V\u00e9nus est visible. Il a fallu quelques prises avant d’avoir le bon r\u00e9glage de luminosit\u00e9. 1\/25\u00e8 100iso 05hr38<\/p>\n

\"\"<\/a><\/p>\n

image 4: la diffraction du lever a bien diminu\u00e9 et les taches solaires apparaissent bien. 1\/200\u00e8 100iso 06hr15<\/p>\n

image 5: 3\u00e8me contact. 1\/800\u00e8 200iso 06hr36<\/p>\n
