Transparency overhead is excellent but all around, below an altitude of about 30 degrees it becomes progressively milkier as you get closer to the horizon.

M9 is round, I’ve got no resolution into stars and there are no bright foreground stars superimposed on the cluster. Lucky to see anything in these conditions.
