Quite like this startrail. One of my better ones. It was the brightest full moon of the year, 29 Jan 2010, and I was concerned the brightness would diffuse the stars. It was a very clear and cold night (-2C) although a few clouds did roll in at 0300hrs and which almost blinded the 15s exposures. I started the camera rolling at 2100hrs and exposed 15s continuous frames all night. Images then stacked in software to produce the stunning visuals of earths rotation. Olympus E3, 12-60mm.
