Seguin Light is a lighthouse in Sagadahoc County, Maine. The nearest town is Phippsburg, about 13.4 km (8.3 mi) away (Seguin Light lies SSE of town). Its recorded tower height is about 16 m (52 ft). It dates from 1795. It is listed on the National Register of Historic Places.
Seguin Light is a lighthouse on Seguin Island, in the Gulf of Maine south of the mouth of the Kennebec River, Maine. Established in 1795, it is the second-oldest of Maine's coastal lighthouses, and the only lighthouse in the state housing a first-order Fresnel lens. With its light at 180 feet (55 m) above mean sea-level, the present tower, built in 1857, is its highest of the state's lighthouses. Automated in 1985, the buildings of the light station are now operated as a museum property by a non-profit organization, and are seasonally open to the public via scheduled ferry from Popham Beach in Phippsburg. The light was listed on the National Register of Historic Places as Seguin Island Light Station in 1977.From the Wikipedia article “Seguin Light”, licensed under CC BY-SA 4.0.

Golden hour & blue hour by month
Lighthouses work at both ends of the day: blue hour when the beacon is lit, and golden hour when white towers take on warm tones.

Local time (America/New York), including daylight saving time. Golden hour runs from about −4° to +6° solar altitude, so the morning golden hour begins during blue hour, before sunrise.
Milky Way & night sky
From Seguin Light, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 3.7 hours on a moonless night), and the core peaks around 17° above the southern horizon. Our light-pollution model puts the sky at about Bortle 3 (rural sky), good enough for detailed Milky Way images.

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: 3 Bortle 3 — Rural sky. Some light domes sit on the horizon, but the Milky Way still looks complex overhead. Modeled zenith brightness ≈ 21.44 mag/arcsec². Aurora needs roughly Kp 5.0+ to show low on the northern horizon here.
Weather & best season
Long-term NASA satellite data for this area show September as the clearest month (about 49% average cloud cover) and January as the cloudiest (73%). August is the warmest month and February 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.
- Shoot RAW to keep the most latitude for high-contrast sunrise and sunset scenes.
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 Fort Popham, Hunniwell Point, 5.7 km (3.5 mi) away. Low tide often reveals tide pools, wet-sand reflections and sea stacks.
