10hr Star Trail

Photo captured overnight 19th/20th March 2022 from my home in South Leicestershire, East Midlands. Full Worm Moon (97%). This star trail was captured and processed all in-camera (no post stacking processing) with the Olympus OM-1 camera & 12-40mm pro II lens. This shot is a massive 10hr long exposure (all captured & processed in camera) and is shows 10 hours of Earth's rotation as shown through the stars, spinning around the North Pole star 'Polaris'. 10hrs was the absolute maximum I could capture between sunset and sunrise the following morning. Read on to see how I captured this shot. BEHIND THE LENS Camera:- OM-1 Lens: Olympus 12-40mm pro II (12mm fl) Tripod Anker PowerBank (PowerCore+ 26800) power device Lens dew heater Live Composite mode - 15s exposure time, F2.8 , 10hrs (1No 4hr + 1 No 6hr shots) ISO 320 I mounted the camera on a fence mount and set up the composition using the fab 12-40 pro II lens framing the horse chestnut tree. For powering such a long exposure I used an external power device, plugged into camera and hung on mount. To prevent ice forming I wrapped a dew heater around the lens (powered from the Anker PD). The star trail was captured by using the Olympus in-camera function called Live Composite (Setting B on top dial). I chose 15s exposures and let the camera shoot for a period of 4 hours. I then repeated immediately for a second period of 6 hours. The only post processing required was to stack the 2 No Live Composites (generated n the camera). The resulting image reveals 10hrs of Earth spinning above a bare conker (horse chestnut) tree.
