Milky Way & night sky
From Mount Constitution Lookout Tower, the Milky Way core is visible in a dark sky from May through July. June gives the longest window (about 2.7 hours on a moonless night), and the core peaks around 12° 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 ≈ 21.38 mag/arcsec². Aurora needs roughly Kp 4.0+ to show low on the northern horizon here.
Weather & best season
Long-term NASA satellite data for this area show July as the clearest month (about 44% average cloud cover) and January as the cloudiest (83%). August is the warmest month and December the coldest, which matters for gear, snow access and how long batteries last at night.

Photography tips for this fire lookout
- Access roads may be rough or seasonal.
- Some lookouts can be rented overnight through recreation.gov, which puts you on site for both sunset and sunrise.
- Shoot the tower itself against the Milky Way or star trails on clear, moonless nights.
- Haze from wildfire smoke can turn the sun deep red but reduce visibility; check air quality.
- Bring a spare battery — cold weather and long exposures drain them fast.
Season: Summer and early autumn; many towers are staffed only during fire season.
Suggested gear: Wide and telephoto lenses, Tripod, Warm layers. Work out exposures with the depth of field, ND filter and NPF rule calculators.
Permits, drones & access
Drones: Drone rules in state parks vary by state and even by park — many require a permit or ban recreational drone flights. Check the park's rules and the FAA B4UFLY app before flying.
