Perseids Meteor Shower 2016

Thursday night (August 11-12) was supposed to be the beginning of the peak of the 2016 Perseids but it was too cloudy to see much.
At least the mosquitoes were glad to see me. I tried again on Friday night (actually early Saturday morning) after the moon set at 2 AM.
I took about 250 30 second exposures and only captured a few meteors. I saw some really nice fireballs but always in a
 different part of the sky from where the camera was pointed. This image is a composite of the Big Dipper region over Lake Oahe.
One image was taken with the star tracker on and one with it off. I replaced the foreground with the foreground from the untracked image.
Then I took meteors captured in the same framing area and transferred them to this image.

One small meteor trail is in the bowl of the Big Dipper, two more in the upper right. There is strong greenish airglow (caused by chemical reactions in the
upper atmosphere) that colors the sky, invisible to us but the camera captures it.
I sure wish I had more meteors to show, but this is it. Sigma 35mm f1.4 art lens, ISO 1600 @ f1.8, Canon EOS 5D
mounted on an iOptron Skytracker.

Here's another Perseid captured near the North American Nebula on the edge of the Milky Way.
