A composite showing the 2017 Geminid meteors streaking from the radiant point in Gemini at upper left, above the blue-white star Castor. 2 or 3 meteors are not Geminids as their paths do not project back to the radiant, but I have left them in regardless, as an illustration. This also illustrates how the meteor paths are shorter closer to the radiant and lengthen away from the radiant. This is a stack of 43 exposures, each 1-minute with the 24mm Canon lens at f/2.5 and filter-modified Canon
