I posted a picture of my coil here: http://home5.inet.tele.dk/f-hammer/firstsp.jpg For those interested. It was shot at 10 in the evening with Olympus OM2n, 30 mm -at- F2.8, however, I forgot to put it in manual mode, therefore it appears to be taken on a cloudy day. It documents 6 feet of spark, and the house isn`t taking the hits, instead, a grounded copper pipe does. Cheers, Finn Hammer
