Cloud ruined star trail
Photo captured overnight 23rd/24th February 2022 from my home in South Leicestershire, East Midlands.
This star trail was captured and processed all in-camera (no post stacking processing) with the Olympus EM1 (iii) camera & 7-14mm lens. Sadly rogue cloud rolled in and ruined the shot.
This shot is an 8hr long exposure (all captured & processed in camera) and is shows 8 hours of Earth's rotation as shown through the stars, spinning around the North Pole star 'Polaris' .
To add a bit of foreground fun to the composition I added some harmless artificial light and created shadowy figures.
Read on to see how I captured this shot.
BEHIND THE LENS
Camera:- Olympus OM-D E-M1 (iii)
Lens: Olympus 7-14mm (7mm focal length)
Tripod
Anker PowerBank (PowerCore+ 26800) power device
Lens dew heater
Live Composite mode - 15s exposure time, F4 , 8hrs (1No 3hr + 1 No 5hr shots)
ISO 320
I mounted the camera on a tripod and set up the composition using a 7-14mm lens framing the horse chestnut tree and the North Star (Polaris). Finding Polaris is easy - Follow the last two stars from the blade of The Plough.
For powering such a long exposure I used an external power device, plugged into camera and hung on tripod.
To prevent ice forming during the 8hrs (ice was forecast 0C) 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 3 hours. I then repeated immediately for a second period of 5 hours.
To create the ghostly shadows I used a torch. Walking around the field (whilst the camera is taking continuous exposures) turning the torch on and off at certain positions, making sure torch was in front of my body, which creates shadows and light. A fun way to add something different to the composition!
The only post processing required was to stack the 2 No Live Composites (generated n the camera).
The resulting image reveals 8hrs of Earth spinning, with a ghostly twist.
