Located in Cumberland County, Maine, Halfway Rock Light is a lighthouse. It sits roughly 16.3 km (10.1 mi) ESE of Falmouth Foreside. Its recorded tower height is about 23 m (75 ft). It dates from 1871. It is listed on the National Register of Historic Places.
Halfway Rock Lighthouse is a lighthouse located on a barren ledge in Casco Bay, Maine. The lighthouse tower, which has a height of 76 feet (23 m), and the attached ex-boathouse are all that remains, as the other buildings have been taken away in storms. The name "Halfway Rock" comes from the position of the rock which is halfway between Cape Elizabeth and Cape Small, the southwest and northeast extremities of Casco Bay, which are about 18 nautical miles (33 km) apart. Halfway Rock Light was added to the National Register of Historic Places as Halfway Rock Light Station on March 14, 1988. Halfway Rock Light Station was purchased in 2014 by a private individual, Ford Reiche, per DIY Network's Building Off the Grid program that shows the reclamation and restoration of the property.From the Wikipedia article “Halfway Rock Light”, licensed under CC BY-SA 4.0.

Milky Way & night sky
From Halfway Rock 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 4 (rural / suburban transition), 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: 4 Bortle 4 — Rural / suburban transition. Light domes are visible in several directions; the Milky Way is clear but lacks detail near the horizon. Modeled zenith brightness ≈ 20.95 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 50% average cloud cover) and May as the cloudiest (66%). 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
- 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.
- Tell someone where you're going in remote areas and carry the ten essentials.
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 Cliff Island, Luckse Sound, 7.3 km (4.6 mi) away. Low tide often reveals tide pools, wet-sand reflections and sea stacks.
