A new perspective to the night sky
This photo is of a star trail and was taken from Lake Eppalock, 25km east of Bendigo, Australia by amateur photographer Lincoln Harrison. He has taken many such photos, positioning 3 cameras a couple of kilometres apart and pointing them at
an empty patch of sky within the Octans Constellation, at the southern celestial pole, around which stars appear to turn a 360 degree circle throughout the night.
Harrison takes a couple of bracketed shots after the sun has set then sets the cameras to open their shutters at 60 second intervals until dawn; during the winter this process takes around 12 hours. He keeps the cameras warm by applying chemical heat sachets every few hours.
