Thanks again for the kind words everyone.
Vivek: Colin didn't explain in detail the technique. You use warp stabiliser which "stablises" motion in video, but in this case it will stabilise on the images and cause them to become aligned. I'm sure you can Google this process, and just apply it to this particular example.
Greg: Yep, everything came together - clear dark skies, minimal Moon interference, and a stronger than average meteor shower. Could be a go'er next year!
Alex: Thanks! Is late, but no harm in trying I guess
