Tully Mountain — a mountain peak in Franklin County, Massachusetts at about 350 m (1,148 ft) above sea level — is a lesser-known subject for landscape photographers. It sits roughly 6.1 km (3.8 mi) WSW of Royalston.
Tully Mountain, 1,163 ft (354 m), is a prominent, steep-sided monadnock located in north central Massachusetts in the town of Orange. It is part of the Tully Mountain Wilderness Management Area. An exposed east facing ledge on the summit provides views of the Millers River valley, Mount Monadnock, Mount Wachusett, and the Wapack Range. The 22-mile (35 km) Tully Trail traverses the mountain. There exists a Tully Mountain (Ireland) that, at 1168 feet above sea level, is almost identical in elevation to the Tully Mountain in Massachusetts. The mountain drains into the Tully River, then into the Millers River, then to the Connecticut River and Long Island Sound.From the Wikipedia article “Tully Mountain”, licensed under CC BY-SA 4.0.

Azimuth is measured clockwise from true north (90° = east, 270° = west). Computed for 2026; values change by less than a degree from year to year.
Golden hour & blue hour by month
Summits catch first and last light — alpenglow can turn rock pink or orange minutes before sunrise and after sunset while valleys stay in shadow.

Local time (America/New York), including daylight saving time. Golden hour runs from about −4° to +6° solar altitude, so the morning golden hour begins during blue hour, before sunrise.
Milky Way & night sky
From Tully Mountain, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 4.0 hours on a moonless night), and the core peaks around 18° 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 ≈ 20.42 mag/arcsec². Aurora needs roughly Kp 5.5+ 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 51% average cloud cover) and December as the cloudiest (68%). 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 mountain peak
- Alpenglow lasts only a few minutes; set up and focus beforehand.
- Clouds around the summit add drama — a clear blue sky is often the least interesting condition.
- Photograph the peak from a lake, meadow or ridge at sunrise when the face that looks east lights up first.
- Long lenses compress ridgelines; shoot the peak from several miles away to make it look massive.
- Bring a spare battery — cold weather and long exposures drain them fast.
Season: Early summer keeps snow on the peaks with green valleys below; autumn adds aspen or larch color in many ranges.
Suggested gear: Telephoto lens, Lightweight tripod, Warm layers, Microspikes in shoulder seasons. Work out exposures with the depth of field, ND filter and NPF rule calculators.
