Stargazing in Denver, US

Denver's Front Range location gives it excellent observing potential — dry continental air, high altitude (1,609m), and rapid access to the Colorado mountains. Bortle 6–7 in the city drops to Bortle 3–4 within an hour heading into the Rockies. Pawnee National Grassland (90 minutes north-east) is a popular dark-sky site on the plains. Winter nights are cold but often brilliantly clear, and Denver's altitude improves seeing and reduces atmospheric absorption.
