Wayne, two of the meteors appear to be tumbling. You can see this as spikes of
brightness along the path. Why the colors? If this is a camera phenomenon,
then all the meteors would show this.
Take Care,
Chris

Hi Chris,
I enjoyed your images of the Perseids and like the line profile idea for the
meteors. Interesting information from it.
Is there a way to convert the amplitude information in the graphs to
magnitudes? I noticed that your bright Perseid seem to saturate the image
because it flat-lined at the top of the curve. Nice!
Also, I was wondering if a couple characteristics I noticed in your images are
real. Does the line profile oscillation indicate that the meteoroids are
tumbling (rotating) and are the CCD integration times that slow in your
camera's readout that your images show alternating red-green-blue streaks?
Glad you had clear skies to make these images. Keep up the good work!
Clear skies,
Wayne (aka Mr. Galaxy)

HI all,
?
Going over 80 automated exposures during the meteor shower, I found 8 meteors
and one Iridium flare on the wide angle frames.? Here are the images, complete
with line profiles for brightness along their length to compare:
