The Best Times for Stargazing in Milliken
Observation in Milliken is most rewarding during the Summer months. During this time, the colder air masses over the Mountain region often result in significantly higher transparency, allowing you to see objects like the Andromeda Galaxy or Orion Nebula with much more definition.
Expert Tips for Milliken 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 (18.0 miles away) remains the benchmark for regional sky quality.
