From the developer:
DSLR Shutter is designed to be a simple tool to capture long-exposure images from digital SLR cameras using their "bulb" setting. It allows you to specify the number of frames, their duration, and various delays to act as a software interval timer for your camera.
It is a cross-platform application with both Windows and OS X versions, supporting both the ShoeString Astronomy DSUSB adapter, serial port, and parallel port triggering.
