Find the Best Places for Stargazing With a Light Pollution Map

Artificial light from cities, towns, and developed areas can make thousands of stars disappear from view. Finding darker skies is one of the most important steps toward enjoying better stargazing and astrophotography.

Light Pollution Map helps you find dark sky locations near you by displaying a detailed light pollution overlay on an interactive map.

Explore the surrounding area, compare locations, and identify places where artificial light pollution may have less impact on your view of the night sky.

Interactive Dark Sky Map

Use the interactive map to explore light pollution levels across different locations.

  • Light Pollution Overlay: Visualize estimated artificial light pollution across the map.
  • Bortle Scale Estimates: Compare approximate night sky darkness levels at different locations.
  • Adjustable Overlay Opacity: Customize how light pollution information appears over the map.
  • Multiple Map Types: Switch between different map views to explore potential observing locations.
  • Horizon Safe Radius: Identify areas with greater separation from surrounding sources of light pollution.

Whether you’re looking for a nearby stargazing spot or planning a trip to a remote dark sky destination, Light Pollution Map helps you make more informed decisions about where to observe.

Bortle Scale Map: Understand How Dark the Night Sky Is

The Bortle Scale is a nine-level system used to describe the darkness and quality of the night sky, ranging from exceptionally dark locations to heavily light-polluted urban skies.

Light Pollution Map provides estimated Bortle scale information to help you compare potential observing locations.

What Do Bortle Scale Ratings Mean?

  • Bortle Class 1: Exceptionally dark skies with outstanding visibility of faint celestial objects.
  • Bortle Class 2: Very dark skies, excellent for observing and astrophotography.
  • Bortle Class 3: Rural skies with relatively low light pollution.
  • Bortle Class 4: Rural-to-suburban transition skies with some noticeable light pollution.
  • Bortle Class 5: Suburban skies where light pollution becomes more significant.
  • Bortle Class 6: Bright suburban skies with reduced visibility of faint stars.
  • Bortle Class 7: Suburban-to-urban skies affected by substantial artificial lighting.
  • Bortle Class 8: City skies where relatively few stars remain visible.
  • Bortle Class 9: Bright inner-city skies with severe light pollution.

Lower Bortle classes generally indicate darker skies, making them especially desirable for Milky Way photography, deep sky observation, and meteor shower viewing.

Bortle classes displayed in the app are estimates. Actual sky darkness depends on local conditions, weather, atmospheric clarity, and nearby lighting.

Milky Way Photography and Dark Sky Location Planning

Want to photograph the Milky Way but aren’t sure where to go?

Light Pollution Map helps astrophotographers locate areas with less artificial light, an important factor when capturing the faint details of our galaxy.

Combine light pollution information with weather forecasts, Moon phases, and astronomical darkness times to plan more promising Milky Way photography sessions.

Whether you’re using a DSLR, mirrorless camera, telescope, or smartphone, finding a darker location can make a dramatic difference in the stars and celestial details you can observe or photograph.

Remember that Milky Way visibility also depends on the time of year, your location, the Moon, and atmospheric conditions.

Live Stargazing Weather Forecasts and Sky Conditions

A dark location isn’t always enough for great stargazing. Clouds, precipitation, wind, and other weather conditions can determine whether an observing session is worthwhile.

Light Pollution Map includes live weather and sky condition information to help you evaluate conditions before heading outside.

Check important weather factors, including:

  • Cloud Cover: Evaluate whether clouds may obstruct your view of the stars.

  • Additional Weather Data: Explore other conditions relevant to your night sky plans.

Use these forecasts alongside the dark sky map to help decide both where and when to go stargazing.

Astronomical Darkness Timer: Know When True Night Begins

Sunset doesn’t mean the sky is immediately dark enough for astronomy.

After sunset, the sky passes through several twilight phases before reaching astronomical darkness, when the Sun is sufficiently far below the horizon for the darkest nighttime conditions under otherwise favorable circumstances.

Light Pollution Map includes an Astronomical Darkness Timer that shows when astronomical darkness begins and ends.
