A composite photo of Cassiopeia taken overnight on 12-13th Aug from Whitstable, UK. It shows 10 Perseids and a faint sporadic (top left) - or possibly as many as 3 are sporadics. As you will realize, this could be logically presented in either landscape or portrait (rotate counterclockwise) format. Ten shots showing meteors and 19 background shots with no meteors were combined, selected from several hundred 30 sec exposures made beteen 10.45pm and 3.45 am: KonicaMinolta Dynax 5D DSLR, 400 ISO, 50mm f/1.8 lens, tracked to maintain field of view over the hours. Processed in DeepSkyStacker and Photoshop. Big learning curve to produce this! I've tried to be as faithful as I could to the data but can guarantee only aproximate photometric consistency accross the whole field of view, as some of the meteors were against thin cloud, and I've had to remove the cloudglow as best I could.
