Jake Mosher (USA). A weathered juniper tree in Montana’s northern Rocky
Mountains is filled with arced star trails and in the centre sits
Polaris, the brightest star in the constellation of Ursa Minor. It took
several test frames of long exposures to make sure that Polaris was in
the right position, but eventually things lined up and the Moon provided
enough light to the foreground, yet plenty of dark skies to allow a
high enough ISO to capture lots of stars.
