Vashon is positioned in a strategic 'Starlight Corridor.' It is far enough from the WA metro glare to allow for deep-sky imaging, yet serves as a convenient staging area for the deeper Class 4 skies found at Obstruction Point.
The Best Times for Stargazing in Vashon
Observation in Vashon is most rewarding during the Summer months. During this time, the colder air masses over the Pacific 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 Vashon Observers
Thermal equilibrium is key. Since Vashon temperatures can shift rapidly after sunset, allow your telescope mirrors at least 45 minutes to 'cool down' before attempting high-magnification work at Covington Community Park. This prevents 'tube currents' from blurring your view of Jupiter or Saturn. Scientific Context: While local conditions vary, the instrumented reading of Bortle 4 at Obstruction Point (55.0 miles away) remains the benchmark for regional sky quality.

Obstruction Point
Olympic NP
Local Relevance
For observers in Vashon, Obstruction Point serves as the definitive baseline for high-altitude transparency and localized skyglow data.
"Perhaps an area 30 degrees in diameter near the zenith offers reasonable visual observations. Otherwise the sky is very modified by light pollution. ZLM 6.9 with difficulty, the eastern sky must be shielded by the ridgetop to achieve this as it definitely affects scotopic vision. The treeless ridge is easy to navigate by the light of the sky. Milky Way easily seen near the zenith,but loses its character rapidly approaching the horizon. Fog appears to move in in early morning through the Strait of Juan de Fuca into the northern Puget Sound area, suppressing light pollution and significantly improving the sky quality."
