There were two brief periods of rainbow forming on the left side of the frame. There are also some lightning flashes far off in the mountains after dark, but it is hard to distinguish them from car lights in the canyon.
I had two cameras going at the time the datura blossoms opened and the full spectrum camera definitely got the event better so it is tacked onto the end.
I'd originally wanted to make a full night time lapse of the meteors, but the clouds really hid the show. By 2:45am there was a significant amount of sky visible, but by then the moon had risen and with the remaining clouds reflecting it, the sky was pretty washed out. I did see a couple nice meteors though :)
