Sky magnitude can vary considerably from one direction in the sky to another. I would expect the area of sky near a moon to be considerably brighter than the area near the Little Dipper.
I actually have a few stars labled on almost every one of my star chart pages, so I can get an idea of the sky in the vicinity of my observation.
When sky is fairly dark mag5, I'm seeing about 40-45 stars in 7x50s. Alsmost twice as many with a 15x70.
There is a small triangle with two bright stars, almost dead center.
Cassiopeia is upside down in the upper left quadrant. it can't bee seen in low powered binoculars. In fact to see the entire asterism needs mag 5.4 skies and 25x100 or better.
