Stargazing Logistics for Florissant
- STEP 1. Primary Staging Area: Stacy Park. This is your most reliable community-vetted hub within a ~9.6 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 St. Louis Astronomical Society for updated site access and group observation schedules.
- STEP 4. Observation Density: There are 5 recognized sites near Florissant offering varied horizons and atmospheric stability levels.
Florissant acts as a primary gateway to the Stacy Park zone. This proximity allows for scientific-grade viewing (Class 4) at Houchin's Field just a short 15-minute drive from the city center, making it a rare 'Hub' for serious observers.
The Best Times for Stargazing in Florissant
Observation in Florissant is most rewarding during the Summer months. During this time, the colder air masses over the Midwest 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 Florissant Observers
Thermal equilibrium is key. Since Florissant temperatures can shift rapidly after sunset, allow your telescope mirrors at least 45 minutes to 'cool down' before attempting high-magnification work at Stacy 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 Houchin's Field (255.1 miles away) remains the benchmark for regional sky quality.

Houchin's Field
Mammoth Cave NP
Local Relevance
Florissant enthusiasts typically use the instrumented readings from Houchin's Field to calibrate their deep-sky expectations for the area.
"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. Limiting magnitude found in Pegasus."
Log Cabins
Fort Donelson NB
Local Relevance
Florissant enthusiasts typically use the instrumented readings from Log Cabins to calibrate their deep-sky expectations for the area.
"SQM of 20.47 at 2035 local time. 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). To the West and Southwest is another lightdome fainter than Clarksville, but brighter than the Milky Way"
