The Best Times for Stargazing in Key Largo

Expert Tips for Key Largo Observers

When observing from Camp Wesumkee / Camp Jackson Sawyer, try to position yourself facing away from the nearest major light dome. For Key Largo residents, this usually means looking toward the rural horizons of FL 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 6 at Boca Chita Key (31.4 miles away) remains the benchmark for regional sky quality.

Regional Perspective: If you're traveling from Islamorada, Village of Islands, the 17.6-mile trip to Key Largo is a justified detour for anyone seeking slightly clearer atmospheric 'seeing'.

"Limiting magnitude star of 6.8 (in Ursa Major) was only seen later in the night (0230) after at least 2 hours of observing time away from the light dome. Warm temperatures helped with visual acclimation. Most all of the local glare sources present the previous night were gone, which also helped the viewing. The entire landscape was well illuminated from the distant light dome."
