The Best Times for Stargazing in Broomfield
In CO, the transitional periods of early Summer often provide a stable atmosphere between weather fronts. For Broomfield residents, this means less 'star twinkling' (scintillation) and a significantly steadier view for high-magnification planetary observation.
Expert Tips for Broomfield Observers
If you're visiting Horsetooth Mtn Open Space, 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 CO during the peak viewing seasons. Scientific Context: While local conditions vary, the instrumented reading of Bortle 6 at Coyote Ridge Parking (36.5 miles away) remains the benchmark for regional sky quality.
