Blue Hill Bay Light — a lighthouse in Hancock County, Maine — is a popular subject for landscape photographers. It sits roughly 11.2 km (7.0 mi) ESE of Sedgwick. Its recorded tower height is about 6 m (21 ft). It dates from 1857.
Blue Hill Bay Light is a lighthouse on Green Island in Blue Hill Bay, Maine. It was first established in 1857. The present skeleton structure was built in 1935. It is also known as "Sand Island Light" or “Eggemoggin Light". The original 1857 structure still stands near the current light. It is a white cylindrical tower with an attached keeper's residence. The lighthouse and cottage were purchased, as part of the purchase of Green Island and its associated land, in 2018 by Green Island Lighthouse, LLC.From the Wikipedia article “Blue Hill Bay 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.

Milky Way & night sky
From Blue Hill Bay Light, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 3.5 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 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. Aurora needs roughly Kp 4.5+ 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 53% average cloud cover) and December as the cloudiest (72%). July 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.
- Bring a spare battery — cold weather and long exposures drain them fast.
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 Center Harbor, 7.2 km (4.5 mi) away. Low tide often reveals tide pools, wet-sand reflections and sea stacks.
