I tried using a program called Starmax to auto detect the meteors but have been unsuccessful so far.
It shows a wide FOV fast lens and high ISO is what is needed for these to be captured on a DSLR. Thanks for taking the time for explaining how to capture them and process them out..
BTW did you have to do much curves adjustment on them to bring them out more?

Yes.. it does take some curves adjustment (brightening) of the meteor sub-frames to get them to stand out. which answers greg's points as well.. the fainter parts of the meteor trail blend away into the background so selecting with magic wand/colour range etc doesn't work.
the very short exposure helps keep the background brightness down (more difficult with a bit of moonlight too) but after the curves adjustment it still makes the background brighter than the base image so just using lighten mode doesn't work.
i think the next step is to try video mode, as the meteors will be recorded just as bright but the background exposure will only effectively be 1/30 sec. not sure how i would process it though!
