Time-lapse Perseids with fading meteors

-A A +A

A view of the night sky of August 12-13, 2013, from Los Alamos, New Mexico. I had the camera take 20-second exposures every 21 seconds. It snapped away from 11:50 until the battery ran out at 4:52 (the timestamps on the images are Pacific time...add an hour for the local time).

I stacked the images with the current image at full intensity and the previous images progressively fading out. As a result, the stars get little, fading tails and the meteors appear then fade.
