L. L. "Stub" Stewart State Park — a state park in Washington County, Oregon — is a rewarding subject for landscape photographers. The nearest town is Vernonia, about 13.5 km (8.4 mi) away (L. L. "Stub" Stewart State Park lies S of town).
L. L. "Stub" Stewart Memorial State Park is a 1,654-acre (669 ha) Oregon state park in Washington County near the community of Buxton. When the park opened in 2007 it was the first new full-service state park in Oregon since 1972. The park includes hiking trails, mountain bike trails, horseback riding, RV and tent campsites, and cabins among other amenities. Located off Oregon Route 47 in the foothills of the Northern Oregon Coast Range, the park connects to the Banks–Vernonia State Trail. Stub Stewart Memorial State Park has been a favorite astronomy spot for amateur astronomers in the area, with organizations such as OMSI hosting multiple star parties at the venue. The site is a great spot for astronomers to set up their telescopes and view the night sky as the trees shield the hilltop from the light pollution from the cities in the area.From the Wikipedia article “L.

Milky Way & night sky
From L. L. "Stub" Stewart State Park, the Milky Way core is visible in a dark sky from April through August. June gives the longest window (about 2.8 hours on a moonless night), and the core peaks around 15° 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 ≈ 20.85 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 July as the clearest month (about 39% average cloud cover) and December as the cloudiest (80%). August is the warmest month and December the coldest, which matters for gear, snow access and how long batteries last at night.
