What this changes

Clear does not always mean dark.

City light scatters through the atmosphere and lowers contrast, even with zero clouds. It now acts as a ceiling on the total score, so perfect weather cannot make a bright city sky behave like a dark rural one.

Still worth seeing

The Moon, planets, double stars, and bright clusters.

Most affected

Galaxies, nebulae, the Milky Way, and faint meteors.

Estimated from the population of Bucharest; local lighting can change the real value by several classes. This is an honest planning estimate, not a live satellite measurement.
