MatУ?riel de prise de vue : TEC 140 + webcam b/w
Commentaires : Venus aureole at egress. Because of bad seeing from my observing location I was not able to capture the ring of fire like in 2004. Nevertheless a very faint aureole on the North Pole of Venus was visible. This image is a composition of a short exposure for the Sun (time 4.46.55 UT) and long exposure for the aureole (time 4.46.28 UT).
