Dark Night Skies
In May 2016 the South Downs National Park became the world’s newest International Dark Sky Reserve (IDSR). We think our star-studded skies overhead are as valuable as our beautiful rolling landscapes and, with properly dark skies in the South East of England under threat, this is a statement that the skies of the South Downs are worth protecting. We celebrate this designation every year at our Dark Skies Festival with two weeks of cosmic fun including star parties, talks and family activities.

How to embrace the darkness
Here are some top tips to help you make the most of stargazing in the South Downs:
- Check the phase of the moon to plan your trip – stargazing is best before a full moon
- Take a blanket or mat to lie on
- Wrap up warm
- Take some snacks and a hot drink
- Take a compass or use the one on your smart phone
- Download a star gazing app to help you identify constellations and stars
- Allow time for your eyes to adjust – this takes around 20 minutes so turn off any lights, torches and put your mobile phone away
What does International Dark Sky Reserve status mean?
- The South Downs National Park is the second IDSR in England and one of only 13 in the world. With 2.2 million people living within 10km of the National Park our reserve is one of the most accessible in the world.
- There are approximately 2,700 streetlights in the National Park. Local lighting authorities are gradually replacing these over time to comply with Dark Sky standards.
- More than 25,000 individual measurements were taken to map the night skies quality across the South Downs. 66 per cent of the National Park has Bronze Level Skies.
In the future the South Downs National Park Authority will use its role as a planning authority to protect the dark skies above the National Park as well as the landscape on the ground. Draft policies for the South Downs National Park’s Local Plan include specific lighting requirements that developers will need to meet.

Nocturnal Wildlife in Your Garden
Dark night skies are not only good for star-gazing, they help nocturnal wildlife such as moths and bats thrive. Here are a few tips on how you can encourage more nocturnal wildlife into your garden:
- Turn off lights when not needed
- Buy lamps under 500 lumens
- Plant paler flowers to attract night-time insects
- Install a batbox
Top tips for photographing night skies:
- Use a tripod.
- With the widest F-Stop available; experiment with ISO settings between 400–1600.
- Use a 10 second delay (self-timer) and set the exposure to around 25–30 seconds – the delay will eliminate button-press shake.
- Try briefly illuminating landscape features in the foreground by quickly flashing a torch.
- Beat the cold. Wrap up warm and take spare batteries!
