The Brecon Beacons Park Society and National Park Authority are hoping a new short film showcasing the park after dark will help the area win accreditation as Wales' first International Dark Skies Reserve.
The film producer Michael Sinclair captured hours of time-lapse footage of the dark skies above the National Park. The film features scenes from the park changing from sunshine to darkness.
Only a handful of international destinations have been granted the Dark Skies award, which would create new opportunities for tourism and the local economy.
It is planned that if the National Park is successful in gaining the accreditation, residents and visitors will be able to understand and enjoy the dark skies. There are currently only two sites in the world that hold International Dark-Sky Reserve status - Exmoor National Park and Mont Megantic in Quebec, Canada. A lighting survey is currently being conducted in the National Park as part of the ongoing accreditation process.
