Hi Glen,
I didn't take it. Explanation can be found by going to the 2005 Perseid
Gallery of the spaceweather.com main page.
Typically though the camera would be mounted on a tracking mount or piggy
backed on a telescope that is tracking. Most tracking mounts alone are
upward of $800 which is pretty darn expensive for a tripod with a couple of
motors and gears attached to the head.
There is an item called a barndoor mount that can be home made. I've never
made on but there are internet links to plans. It's basically two pieces of
wood that are hinged together. A screw is used to continually adjust the
orientation of the camera as the earth turns. Crude, but apparently works
when done well, with shorted time exposures.

Was taken with a Canon 20Da (modified for astronomical purposes to allow
better reds).
The meteors are cool, but the background is very nice also. What sort of
tracking system are you using with the camera? I've always wanted to try
this sort of thing someday. Is there some inexpensive system, perhaps
something homemade, which will make a camera track the stars during long
exposures?
thanks,
Glen
