Local Observation Strategy

Washington is positioned in a strategic 'Starlight Corridor.' It is far enough from the IN metro glare to allow for deep-sky imaging, yet serves as a convenient staging area for the deeper Class 4 skies found at Houchin's Field.

The Best Times for Stargazing in Washington

While Winter offers the most consistent clear nights for Washington, wait for the 4-day window surrounding the New Moon each month for the deepest contrast. Since the sun sets early in the late Winter months, you can often begin deep-sky imaging as early as 7 PM.

Expert Tips for Washington Observers

When observing from Wahnsiedler Observatory, try to position yourself facing away from the nearest major light dome. For Washington residents, this usually means looking toward the rural horizons of IN 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 4 at Houchin's Field (118.9 miles away) remains the benchmark for regional sky quality.

Regional Perspective: Washington is situated just 19 miles from Vincennes, but its local horizon often provides a more stable viewing experience for planetary targets.

"Dewfall occurred during data collection, however dew heater prevented lens fog. Multiple light domes evident from site, as well as a continuous glow along horizon in all directions. Airglow was present. Andromeda galaxy easily visible, Beehive (Pegasus) visible with medium effort. Prominent dust lanes in Milky Way visible at zenith, but not below ~50 degrees."

"Only fair transparency and seeing. Some fast moving clouds. High humidity. Milky Way visible from 20 degrees above north horizon. Great rift visible, Saggitarius cloud not easily visible, Scutum cloud not visible. Milky Way about 10-12 degrees wide, but faint and no fine details. To the NW a blue white light dome easily seen. Due East is the Clarksville lightdome almost 25 degrees high and 15 degrees wide. Core is bright. Adjacent to the light dome is a spotlight (which we determined was coming from the cemetary here in FODO park)."
