Sky Brightness: mag/arcsec², Darkness Classes & Limiting Magnitude
This lesson is part of the course
In this lesson
You average sky-meter readings for six sites, sort them into the club's fictional darkness classes with an approximate XLOOKUP, estimate the faintest star visible to the naked eye and compare each site's sky glow with the club's darkest site.
