Transit of Venus, a rare silhouette against the Sun
In the winter of 1768, the Royal Society petitioned King George III to finance a scientific expedition to the Pacific ocean to study and observe the transit of Venus across the Sun to enable the measurement of the distance from the Earth to the Sun. James Cook departed from Plymouth on 26 August 1768 and the ship rounded Cape Horn and continued westward across the Pacific ocean to arrive at Tahiti in the spring of 1769, where the observations were to be made. It was a rare, very rare event and would not have wanted to miss a unique opportunity like that.
The same reason that led me this morning to get up at 4 am, ride on my Vespa for to see Her and Sun rise together above the hills. I was waiting them with my tripod and reflex near the lighthouse of the promontory of Portofino, in the Ligurian east coast; the weather was not so good, but I was fully immersed in the nature, a terrace spectacular sea, an unforgettable sight! My Neutral Density 400 and Infrared R72 filter have been crucial to the success of the picture, without them there would have been possible. I have taken over ninety pictures this morning, I was very pleased and fortunately the sky became cloudy around the end of the transit; I have certainly been lucky. I have known that the next one will take place only in the 2117, so that it has been really the only opportunity to witness this unique spectacle.
