Night Sky, Salisbury Plain

22/03/2015
This image of the whole night sky was made using an 8mm focal length fish-eye lens on my Canon 5D Mark III. I placed the camera flat on its back in the centre of an almost complete circle of trees high on Salisbury Plain and captured a continuous sequence of 86 frames, each exposed for 30 seconds. By combining all 86, the resulting image shows the entire night sky as the earth rotates over a period of 43 minutes. The brightest trail, just above centre, is that of Jupiter, whilst Venus sits low on the western horizon and Sirius is in the north-west. Two meteors can be seen crossing the star trails. For a short duration exposure at the same location, giving an image of the night sky as seen by eye, see my Night Sky Gallery.
