I learned a lot shooting the Perseid Meteor shower. I needed thee kinds of shots:
Finally don't sort your images when you haven't slept for over 24 hours! My shots were a little underexposed to pick out fainter meteors. With over exposure, it is easy to loose the transition in color from blue to red as they slow down in the atmosphere. After filtering out the shots with airplanes and car lights, I'm pleased with the final result.

The coolest thing that I realized from this project is that, when not over exposed, each meteor makes a little rainbow along its path. Hot blue or green at the start while it is still moving fast and ending up red as it slows down and melts away. By eye they are so quick and bright or dim I don't notice much color except at the end. My earlier camera meteor images and most others that I've seen must be overexposed blowing out any color.
Once I got rid of the airplanes and satellites, I could see that all the meteor trails point (blue end) to the radiant in Perseus. I'm surprised by how many photographs of the Perseids that I've seen where their directions are random or concentrated in some other part of the sky. I suppose operator error or creative license...
The Photoshop composite file has thirty-seven layers. When I tried to save it, I hit the dreaded Photoshop 2GB limit, but it saved nicely as a 1GB PSB large document format file. Yes, OS X has a 8,000,000,000 GB file size limit, but Adobe says it all.
