Cotesbach Star Trail

Cotesbach StarTrail 05/06 April 2015, Leicestershire, UK. First star trail at my new house in Cotesbach. I have a wonderful horse chestnut tree which is a great foreground subject. 8 hours and justst under 2000 exposures Star Trail captured with Olympus OM-D E-M5 & 7-14mm lens. The image is composed around the North Star (Polaris), the pole star around which all others spin.
How did I capture it? - Camera on tripod F4, ISO 320, 15s. Manual focus set to infinity I composed the image around the North Star (Polaris) to ensure a swirly star trail above the trees. The first shot was captured/exposed through the lcd screen and then using the remote cable (set to lock) and turning off lcd (maximise battery) I depressed shutter. This allowed the camera to shoot continuous for 8 hours (using 2 battery pack). I transferred all images (High res JPEG) to MAC and imported/stacked in StarStax software. Plane trails removed using Pixelmator software. The final composite reveals 8 hrs of Earth spinning, as shown through the stars.
