I live in a Class-5 night sky on the Bortle Scale, and you cannot see the Milky Way with your naked eye here. I was wondering what Class night sky I would have to be in to see the Milky Way's gas and dust clouds with my naked eye?
According to the Wikipedia article on Bortle scale, at class 5 light pollution
the Milky Way is very weak or invisible near the horizon, and looks washed out overhead
The brightest pollution level where the Milky is visible is described as class 6, bright suburban sky:
the Milky Way is only visible near the zenith.
At higher level, 7, suburban/urban transition,
the Milky Way is nearly or totally invisible.
