The Best Times for Stargazing in Lackland AFB
In TX, the transitional periods of early Autumn often provide a stable atmosphere between weather fronts. For Lackland AFB residents, this means less 'star twinkling' (scintillation) and a significantly steadier view for high-magnification planetary observation.
Expert Tips for Lackland AFB Observers
If you're visiting Raymond Rimkus Park, bring a pack of chemical hand-warmers and rubber-band them to your eyepiece or camera lens. This acts as a 'budget' dew heater, which is essential for the humid nights often found in TX during the peak viewing seasons. Scientific Context: While local conditions vary, the instrumented reading of Bortle 3 at LBJ Ranch Dales Trap (60.0 miles away) remains the benchmark for regional sky quality.
