i have a sony dslr a100 and want to take pix of the meteor showers tonight. i have taken pix of lightning and stars with my previous sony cybershot on a tripod using the bulb setting. on my dslr a100, i set it on a tripod and try to press the button and the shutter doesnt respond at all. since im taking pix of the stars, i wouldnt use a flash obviously. can anyone tell me what i'm doing wrong? i can offer more info if asked. i wanted to get this posted as fast as possible.

thanks much
terri
