Local Observation Strategy

Greentree is positioned in a strategic 'Starlight Corridor.' It is far enough from the NJ metro glare to allow for deep-sky imaging, yet serves as a convenient staging area for the deeper Class 5 skies found at Meadow south of Church House.

The Best Times for Stargazing in Greentree

Observation in Greentree is most rewarding during the Spring months. During this time, the colder air masses over the Appalachia region often result in significantly higher transparency, allowing you to see objects like the Andromeda Galaxy or Orion Nebula with much more definition.

Expert Tips for Greentree Observers

Thermal equilibrium is key. Since Greentree temperatures can shift rapidly after sunset, allow your telescope mirrors at least 45 minutes to 'cool down' before attempting high-magnification work at Valley Forge National Historical Park, Model Airplane Field. This prevents 'tube currents' from blurring your view of Jupiter or Saturn. Scientific Context: While local conditions vary, the instrumented reading of Bortle 5 at Meadow south of Church House (47.8 miles away) remains the benchmark for regional sky quality.

Regional Perspective: If you're traveling from Ashland, the 2.9-mile trip to Greentree is a justified detour for anyone seeking slightly clearer atmospheric 'seeing'.

"Site next to Wick House in a field north of the orchard. Seeing very good, transparency fair. Very humid, dew on the grass. No part of the sky is dark, a gradient of sky brightness from horizon to zenith. The sky is grayish white, near the NYC and Newark light dome some peach color seen. Very bright near the horizon, which is actually at least 10 degrees above the true horizon. The site is in a "hollow" and has tall trees all around, so the brightest parts of light domes are masked. No distinct "domes" are seen, the sky is bright all around except toward the west, which looks dark by comparison. It is therefore impossible to attribute light pollution to any individual city. The Milky Way is not at the zenith at this time of the year, but even late when the summer Milky Way is higher it is invisible. Near the zenith there are some features, the Coma cluster is seen as 10-12 stars, the form of Ursa Major and Leo are readily seen, but anything below 60 degrees above the horizon is severely compromised. The land is well illuminated, navigation easy unless you are looking toward New York and Newark, where the light of the sky produces glare. Estimate about 1/4 of scoptopic vision is lost, unless looking at the eastern sky, which is much brighter. Bortle Class 7, could be 6 later on if it gets a bit darker. With patience, remarkably ZLM of 5.9 is achieved."
