i'm certainly no expert on shooting meteors...i've tried a few times. but you're going to want to open up your lens more...use a higher ISO as well...the rule to avoid star trails is 500or 600 divided by your focal length= the longest amount of time in seconds you can keep open your shutter
what i've found works best is to take shots consecutively an to aim for a short shutter speed that you can get away with and still expose the stars...this way if one streaks by it will end up being brighter in the image...of course nobody knows where the streak will come, so it's a bit of luck required to get something good
should be more out tonight to give it another go
