Although some of the meteors were quite bright to the unaided eye, I had to progressively crank up the ISO setting to record anything at all, ending up at ISO3200 using an 8mm wide-angle at f4.5. At this high sensitivity I knew the sky-glow would be difficult to keep under control, so limited myself to 10 second exposures.
Of the few hundred images taken, I was chuffed that a handful had the tell tale streaks of meteors.
This image is a composite of several of these. It was a job to orientate and register the separate images correctly, since the constellations distorted due to the wide-angle lens as the stars moved across the sky.
The red lines show the tracks of the meteors converging back to their origin, as best as I could estimate these, to show the region of the radiant. The variation in radiant positions is due to the distorting effect of the lens making it impossible to accurately represent the curved sky on a 2-dimensional flat image, for meteors that were widely separated on the image, but they appear to radiate from just NW of the star Castor, the head of one of the twins.
