Washington
Stargazing Guide.
Uncover the hidden celestial treasures of Washington, IN. From the verified horizons at Wahnsiedler Observatory to the scientific Bortle Class 4 reports at Houchin's Field, your journey to the stars starts here.
Stargazing Logistics for Washington
- STEP 1. Primary Staging Area: Wahnsiedler Observatory. This is your most reliable community-vetted hub within a ~33.1 mile radius.
- STEP 2. Sky Quality Baseline: Classified as Class B (Rural). Use the instrumented 4 rating from Houchin's Field as your technical benchmark for the region.
- STEP 3. Local Support: Contact Evansville Astronomical Society for updated site access and group observation schedules.
- STEP 4. Observation Density: There are 5 recognized sites near Washington offering varied horizons and atmospheric stability levels.
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.
Best Spots for Stargazing in Washington
The most accessible and reliable viewing locations in the region, ranked by local observer feedback. To get the most out of these verified spots, ensure your mobile reconnaissance kit is ready for Washington's local horizons.
Wahnsiedler Observatory
" Washington observers often find this mid-distance site perfect for a full session. Sky Contrast Tip: To see the Milky Way, wait for the Moon to go below the horizon; even a 25% crescent Moon can wash out the faintest nebulae. "
Patoka Lake Newton-Stewart Beach
" A manageable drive from Washington, this spot is a reliable regional favorite. Deep Sky Advice: Allow at least 20 minutes in total darkness for your pupils to fully dilate. You'll notice faint nebulae that were invisible at first. "
Dubois 4H Fairgrounds
" Washington observers often find this mid-distance site perfect for a full session. Imaging Tip: If you're photographing the Milky Way, bring a clear filter or dew shield to prevent lens fogging in humid conditions. "
Angel Mounds
" Pack some snacks for the drive from Washington; this destination is a justified detour. Meteor Watching Tip: Don't look at one spot; keep your eyes moving across the sky. Your peripheral vision is more sensitive to motion. "
Washington Carnegie Public Library
" A short hop from Washington, this spot is a top-tier local choice. Imaging Tip: If you're photographing the Milky Way, bring a clear filter or dew shield to prevent lens fogging in humid conditions. "

Houchin's Field
Mammoth Cave NP
Local Relevance
Washington enthusiasts typically use the instrumented readings from Houchin's Field to calibrate their deep-sky expectations for the area.
"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."
Log Cabins
Fort Donelson NB
Local Relevance
Washington enthusiasts typically use the instrumented readings from Log Cabins to calibrate their deep-sky expectations for the area.
"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)."
