Stargazers are hoping that a remote corner of the North East will become Europe's largest Dark Sky Park.
The Northumberland National Park, Kielder Water & Forest Park Development Trust and Kielder Observatory Astronomical Society are to apply to the International Dark Skies Association (Ida) to get the special status.
The title would designate the area as an ideal location to view the stars because light pollution is extremely low.
Other parts of the UK such as Exmoor and the Brecon Beacons are dark sky reserves, not parks, which have less stringent rules.
Europe's largest Dark Sky Park is in Galloway, Scotland, but the Northumberland bid would cover a larger area.
Hundreds of light meter readings have been taken around the national park, as part of the bid to the Ida.
Originally, just Kielder Forest was to apply for the coveted status, but that has been extended to the whole of the national park.
Residents have been reassured that if Dark Sky Park status is won, it will not mean they have to switch off lights at night.
It will mean that new buildings will have to use less light-polluting external fixtures, where light shines downwards and not beyond property boundaries.
The status could boost tourism and increase visitor numbers to Kielder's already-popular observatory.
Light pollution from street lamps and homes spoils the night sky for astronomers by significantly reducing the number of visible stars.
