This one was my very first try of a full Milky-Way shot.
Though it appears as an arc, the Milky-Way is actually a straight line, seen from our view point in/on the galaxy. The arc shape is due to distortions created by the lenses used. As the horizon usually appears a straight line to us (though it actually isn't), adjusting such an astro image results in this particular arc shape.
This was taken in Paekakariki, in a night with a half Moon out, which makes astro photography in general difficult. It is a panorama created from 19 single shots.
Of course this one is available in printed version, please contact me if you're interested
