Perseids 2017

I tried to catch some meteors from my backyard in the night from 11 to 12 of August. Haze and Moon make the sky to glow so I mentioned only several brightest meteors by eye (one of them was definitely not Perseid).

Using Canon EOS 600D with kit lens in the night from 11 to 12, after 1 a.m. local time I managed to catch two bright meteors: at 1:17 (brighter) and at 1:36.

The brightest meteor passed near Little Dipper (left). A part of Cassiopeia W is in the bottom-right corner.
