It would be interesting to learn how the composite photo was created. There are no star trails visible and it appears that the meteor trails were added to the sunset photo. But how do you extract a meteor flash from subsequent photos and add it to the original? All the background star positions would have changed over the four hours, so you would have to isolate the meteor trails without any background sky.

The telescope tracked the stars, the streaks were transient and got painted on over the four hours.
