This is a picture that was taken during approximately 1.5 hours on Mauna Kea, Big Island, Hawaii. In the foreground, you can see the Canada France Hawaii Telescope. On Mauna Kea, nights are amazingly clear and dark. The picture consists of 22 single frames, each taken at f/4, ISO 100, 16 mm and exposure time of a little more than 4 minutes, which makes it a total 90 minutes exposure. I stitched the pictures in Photoshop to create this image.
