Bishop and Clerks Light is a lighthouse located in open water on Bishop and Clerks Rocks, about two nautical miles south of Point Gammon in Hyannis, Massachusetts, United States. The light was established in a granite tower in 1858. It was automated in 1923, deactivated five years later and demolished in 1952. It was replaced with a white 30-foot pyramidal day beacon. The day beacon was replaced with a round, orange and white 30-foot tower placed on top of the original Bishop & Clerk's granite base in 1998.From the Wikipedia article “Bishop and Clerks Light”, licensed under CC BY-SA 4.0.

Milky Way & night sky
From Bishop and Clerks Light, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 4.5 hours on a moonless night), and the core peaks around 20° above the southern horizon. Our light-pollution model puts the sky at about Bortle 5 (suburban sky), so expect visible sky glow; drive away from towns for better results.

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: 5 Bortle 5 — Suburban sky. The Milky Way is weak near the horizon and washed out overhead; long exposures pick up a sky glow. Modeled zenith brightness ≈ 20.37 mag/arcsec². Aurora needs roughly Kp 6.0+ 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 January as the cloudiest (69%). 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
- 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.
- Stormy weather and crashing surf add drama; keep a safe distance from waves on rocks and piers.
- A telephoto from across a bay compresses the tower against cliffs or the moon.
- 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
