"Shoestring" isn't really a technique; it's just a way to associate a meteor to
its radiant. Usually, a shoestring is made to attach your shoe to your foot. But
amator astronomer are really ingenious, ans because all they use can be used for
astronomy, shoestring is used by meteor observers... Very easy. I don't know if
a site is dedicated to shoestring use in meteor astronomy, but may be useful
;-)) First you secluded a shoedtring from a shoe (preferably one you don't use
often, otherwise you might have difficulties to walk later ). As said
previously, a dark shoe string is preferable to a white one, because a dark one
is easier to see in the sky ( I just used a dark blue one during the Perseid,
will try with a clear one one of these day, just to see what it gives ). When
you have your shoestring in hand, and when you're comfortably observing meteor,
you wait one of these shooting stars... When one came in your field of view, you
put the shoestring on the apparent path of the meteor, and you see where do this
shoestring led to, so where the meteor came from in the sky. If it hit the
radiant, you just have to check the speed of the meteor to really be able to say
that it's a member of a determined radiant ( this has just been explained in
previous mails ).
Very simple... But amator astronomers are really ingenious personns ;-))
Clear skies !
