Milky Way & night sky

From Gibson Woods Nature Preserve Dune and Swale Complex (Minor), the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 4.5 hours on a moonless night), and the core peaks around 20° above the southern horizon.

Photography tips for this sand dunes

  • Protect gear from blowing sand; avoid changing lenses in the wind.
  • Sand surfaces get extremely hot in summer afternoons.
  • Walk along ridges rather than across faces to avoid leaving footprints in your future compositions.
  • A telephoto isolates S-curves and layered ridges.
  • Bring a spare battery — cold weather and long exposures drain them fast.

Season: Spring and autumn for comfortable temperatures; full moon nights give soft light on the sand.

Suggested gear: Telephoto lens, Lens blower, Sun protection, Water. Work out exposures with the depth of field, ND filter and NPF rule calculators.
