The Best Times for Stargazing in Fort Washington
In PA, the transitional periods of early Spring often provide a stable atmosphere between weather fronts. For Fort Washington residents, this means less 'star twinkling' (scintillation) and a significantly steadier view for high-magnification planetary observation.
Expert Tips for Fort Washington Observers
Thermal equilibrium is key. Since Fort Washington 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 (30.8 miles away) remains the benchmark for regional sky quality.

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