      Explanation: Meteors from the Kappa Cygnid meteor shower are captured   
      in this time-lapse composite skyscape. The minor meteor shower, with a   
      radiant not far from its eponymous star Kappa Cygni, peaks in   
      mid-August, almost at the same time as the much better-known and   
      better-observed Perseid meteor shower. But, seen to have a peak rate of   
      only about 3 meteors per hour, Kappa Cygnids are vastly outnumbered by   
      the more popular, prolific Perseid shower's meteors that emanate from   
      the heroic constellation Perseus. To capture dozens of Kappa Cygnids,   
      this long term astro-imaging project compiled meteors in exposures   
      selected from over 51 August nights during the years 2012 through 2024.   
      Most of the exposures with identified Kappa Cygnid meteors were made in   
      August 2021, a high point of the shower's known 7-year activity cycle.   
      All twelve years worth of Kappa Cygnids are registered against a base   
      sea and night skyscape of the Milky Way above Elafonisi Beach, Crete,   
      Greece, also recorded in August of 2021.
