|So what can you do with GigaPixel images besides zoom in on them on webpages?

From the 25 th August to the 13 th September 2009, this giant picture of the entire sky is exposed in the « Un ciel pour une planète » exhibition, in the Atrium of the Monte-Carlo Casino, Monaco. The making of of the project is shown under a 12 m x 6 m picture.|
According to the last stellar census made by astronomers at the Besançon Observatory, the Milky Way contains about 150,000 million stars. Less than 0.0001% of these are visible here, and astronomers have, today, identified less than one percent of the total galactic population.
This image of the sky is in fact a mosaic composed of almost 300 fields, each captured four times, for a total of 1200 photos. All were taken with a Nikon D3 digital camera and its 50 mm lens open at f5.6.
Each image is the result of a 6-minute exposure. The apparent motion of the sky, caused by Earth’s rotation, was corrected thanks to a small equatorial mount, moving in the opposite direction and making a whole circle in 24 hours precisely around the Earth’s axis of rotation.
"Lying on the ground, at the foot of the telescope, rocked by the regular “bip bip” of the interval timer, I gazed at the sky, as the amazing stellar clouds of the Milky Way passed over me. From time to time, the “clac” announcing the end of an exposure woke me up, when it was not the chilling cold of the night.
I lived in this way for almost thirty nights, in complete osmosis with my camera and the sky, and heard about 1200 times the “bip bip” announcing the next exposure… The total exposure time of this image is close to 120 hours."
