This image of the sky is really a mosaic consisted of about 300 photographed fields each four times, what represents right by 1200 photos there. All were taken with a digital case Nikon D3 and its objective of 50 mm of focal diaphragmé in 5,6.<p>Every image was exposed for 6 minutes, the visible movement of the sky, due to the rotation of the Earth, being corrected by a small equatorial frame, the axis of rotation of which, turning in 24 hours, in the inverse direction of the movement of the Earth, was strictly aligned on the axis of rotation of our planet.<p><a href="http://sergebrunier.com/gallerie/pleinciel/" rel="nofollow">http://sergebrunier.com/gallerie/pleinciel/</a>
Does any one have any idea why there would be 14 "rays" coming off each of the bigger stars?<p>Also, Microsoft's WorldWide Telescope is one of the best "Google Earth for outer space" things I've seen.
