Leo, I cannot see the point in searching for a radiant
from two meteors. Two meteors will always meet somewhere.
Also, note that the prolongations of meteors are great
circles. These are not straight lines on a map like the
one you showed. They have to be curved. Meteors (and their
prolongations) are straight lines only on gnomonic maps.
Nevertheless, nice photos! I also tried to capture a few,
but nothing spectacular.
Best regards,
Rainer
