Explanation:
Frames from a
camera
that spent three moonless nights under the stars
create this composite night skyscape.
They were recorded during August 11-13
while planet Earth was sweeping
through
the dusty trail
of comet Swift-Tuttle.
One long exposure, untracked for the foreground, and the many
star tracking captures of Perseid shower meteors
were taken from the village of Magyaregres, Hungary.
Each aligned against the background stars,
the meteor trails
all point back to the annual shower's radiant in the constellation Perseus
heroically standing above this rural horizon.
Of course the comet dust particles are traveling along trajectories
parallel to each other.
The radiant effect is due only to perspective, as the parallel tracks
appear to
converge
in the distance against the starry sky.
