The Best Times for Stargazing in Cudahy

Expert Tips for Cudahy Observers

When observing from Garvey Ranch Observatory, try to position yourself facing away from the nearest major light dome. For Cudahy residents, this usually means looking toward the rural horizons of CA 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 7 at Tuna Canyon Park (25.3 miles away) remains the benchmark for regional sky quality.

Regional Perspective: Cudahy is situated just 2.3 miles from Huntington Park, but its local horizon often provides a more stable viewing experience for planetary targets.
