Located in Plaquemines Parish, Louisiana, Frank's Island Light is a lighthouse. The nearest town is Belle Chasse, about 123 km (76 mi) away (Frank's Island Light lies SE of town). It dates from 1823.
The Frank's Island Light was an early lighthouse in Louisiana, marking the entrance channel to the Mississippi River from the delta. Conceived of as a grand monument, it suffered from construction issues and was eventually abandoned as the channel it marked was supplanted by other routes.From the Wikipedia article “Frank's Island Light”, licensed under CC BY-SA 4.0.

Milky Way & night sky
From Frank's Island Light, the Milky Way core is visible in a dark sky from February through October. June gives the longest window (about 6.7 hours on a moonless night), and the core peaks around 32° above the southern horizon. Our light-pollution model puts the sky at about Bortle 2 (typical truly dark site), which is excellent for astrophotography.

Window when the galactic core is at least 10° high during astronomical darkness on the 15th of each month. Pick nights within a few days of the new moon. Plan exact nights with the Milky Way planner.
Estimated sky darkness: 2 Bortle 2 — Typical truly dark site. The summer Milky Way shows rich structure; clouds look like black holes in the stars. Modeled zenith brightness ≈ 21.86 mag/arcsec².
Weather & best season
Long-term NASA satellite data for this area show October as the clearest month (about 40% average cloud cover) and January as the cloudiest (67%). August is the warmest month and January the coldest, which matters for gear, snow access and how long batteries last at night.

Photography tips for this lighthouse
- A telephoto from across a bay compresses the tower against cliffs or the moon.
- Many lighthouses are on private or Coast Guard property — check public access and opening hours.
- Moonrise or the Milky Way over the tower makes a classic night composition; plan with the azimuth tables.
- During blue hour, use 5–15 second exposures to capture the beam; check whether the light is still active.
- Shoot from the beach or a jetty to place the tower against open sky and sea.
- Scout in daylight if you plan to shoot at night or before sunrise.
Season: Summer brings open towers and tours; autumn and winter offer storms, fewer crowds and lower sun angles.
Suggested gear: Tripod, Telephoto lens, ND filter for smooth water, Rain cover. Work out exposures with the depth of field, ND filter and NPF rule calculators.
Tides
The nearest NOAA tide prediction station is Southeast Pass, 3.5 km (2.2 mi) away. Low tide often reveals tide pools, wet-sand reflections and sea stacks.
