Milky Way & night sky
The Milky Way's bright core (in Sagittarius) barely clears the southern horizon at this latitude, so focus on winter Milky Way, aurora or star trails instead.

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: 1 Bortle 1 — Excellent dark-sky site. The Milky Way casts faint shadows; zodiacal light and airglow are obvious. Modeled zenith brightness ≈ 21.95 mag/arcsec². Aurora needs roughly Kp 0.5+ to show low on the northern horizon here.
Weather & best season
Long-term NASA satellite data for this area show February as the clearest month (about 71% average cloud cover) and June as the cloudiest (79%). July 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
- 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.
- Check road and trail conditions with the managing agency before you go.
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.
