The night sky taken with from Toolangi on the 6th of April. The camera was place on its back and the shutter was opened 15 Seconds with the lens fully opened. I discovered times longer than 15 seconds made the movement of the earth too obvious and the photo also became over exposed with the lens completely open. One other problem can be seen on the photo is the vignetting in the corners of the image and the softness around the edges, which are a result of a fully open lens. I believe programes like stacker will produce much better results by combining a number of images.
