How dark the sky really is at Town of Breckenridge, Colorado
Modelled zenith brightness at the site's coordinates is 20.26 mag/arcsec², which maps to roughly Bortle 5 (what each level means). This is an approximation from the 2024 light-pollution atlas, not a field measurement — and it describes the single point DarkSky lists, not the darkest corner of the community.
Modelled zenith brightness puts this spot at Bortle 5 — a suburban sky where the Milky Way is only faintly visible at best. The international dark sky community designation recognises responsible lighting and education, not a pristine sky; the Moon, planets, double stars and bright clusters are the realistic targets, and the atlas value at the site centre may not reflect its darkest corners.
