Video allsky image of Perseid shower over Colorado, on the evening of August 11/12. This shows 85 Perseids (non-Perseids have been removed) captured between dusk and dawn. The count is a bit low since we're still in the monsoonal weather pattern, and there were scattered clouds throughout the night as well as some thin haze.
The shower peaked locally between 1am and 4am, and most of the captured meteors fell in that interval. Given the high radiant declination (just 30° from the pole), three hours just isn't long enough for the radiant to drift all that much, which makes its general location very obvious from apparent origin of the meteors in this image.
