Venus Transit

June 8, 2004




On June 8th 2004 this rare celestial event took place again and it was perfectly observable from the Netherlands. For my observation site the circumstances where perfect, starting at 15° altitude and ending at 61° altitude, I could see the whole transit from my backyard.

I decided to devide the whole transit into three parts, the ingress, the path of Venus over the Sun and the egress.



The ingress was captured with my 150mm Newton telescope in prime focus (F=940mm) with a Baader sunfilter and a ToUcam Pro.
During the ingress I made 1 image/second each with an exposure time of 1/100s.

At the end of the ingress the so called black drop effect could be seen.

The path of Venus over the Sun was captured with a 250mm telelens with a Baader sunfilter and a ToUcam Pro. During this session I made 1 image per 15 seconds each with an exposure time of 1/1000s.

The egress was captured with my 150mm Newton telescope and 2x barlow (F=2400mm) with a Baader sunfilter and a ToUcam Pro.
During the ingress I made 1 image/second each with an exposure time of 1/33s.
