The Best Times for Stargazing in Surprise
In AZ, the transitional periods of early Summer often provide a stable atmosphere between weather fronts. For Surprise residents, this means less 'star twinkling' (scintillation) and a significantly steadier view for high-magnification planetary observation.
Expert Tips for Surprise Observers
If you're visiting Stage N Castle Hot Springs, bring a pack of chemical hand-warmers and rubber-band them to your eyepiece or camera lens.
