Expert Tips for Lansdale Observers
When observing from Valley Forge National Historical Park, Model Airplane Field, try to position yourself facing away from the nearest major light dome. For Lansdale residents, this usually means looking toward the rural horizons of PA to capture the lowest magnitude stars that are normally invisible from the city center. Scientific Context: While local conditions vary, the instrumented reading of Bortle 5 at Meadow south of Church House (25.9 miles away) remains the benchmark for regional sky quality.

Jockey Hollow
Morristown NHS
Local Relevance
The scientific findings at Jockey Hollow provide Lansdale residents with the most reliable data on regional atmospheric stability.
"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."
