Perseid!

Ka-pow! Another piece of space flotsam slams into the upper atmosphere at supersonic speed. This one, a remnant of comet 109P Swift-Tuttle encounters us at something like 58 kilometers per second. I had left the camera continuously exposing Saturday night, and the following Tuesday after Andy had set his DSLR going I had another crack of the whip. 13 second exposures seemed about right. I got lucky. Soon after starting I caught a Perseid meteor shooting through Cassiopeia, then I got even luckier with this substantial one. However I missed seeing it due to my strange posture while setting up the camera. I had just repositioned it on the ground and clicked the remote. After a few seconds, Andy exclaimed something and my shutter closed. He had seen it while looking about 90 degrees away - so it must have been pretty bright. The first I knew of it was the strange little white line that had appeared on the preview screen. It looks like it's slamming into the top of the tree and the glow from Norwich seems to add an aesthetically nice balance to the photo. Here is the single 13 second shot, with no processing.
