Washington
Stargazing Guide.
Just 31.8 miles from the center of Washington, lies some of the region's best viewing at Jefferson College Observatory. We feature instrumented readings from Houchin's Field to guarantee the most accurate sky quality data.
Stargazing Logistics for Washington
- STEP 1. Primary Staging Area: Jefferson College Observatory. This is your most reliable community-vetted hub within a ~31.8 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 Astronomical Society of Eastern Missouri 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 MO 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 Jefferson College 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 MO 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 (283.1 miles away) remains the benchmark for regional sky quality.

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)."
