The DSUSB is a USB peripheral for your computer that allows software to control your camera’s shutter. In addition to the DSUSB, you will need a cable that is appropriate for your camera. The USB cable on DSUSB is 3 feet long.
Cables to suit Canon EOD and Nikon cameras are available.
Shoestring USB Shutter Control
Many people are now using Digital SLR cameras to take amazing deep-sky astrographs. Using the camera’s internal shutter control typically limits the exposure time to 30 seconds. To get longer exposure times, the bulb stop (B) of the camera must be used. In bulb mode, the shutter is controlled by a remote control. If you wish to use a computer to generate the remote control commands, the products on this page will allow you to do so when used with appropriate software that supports this adapter.
Compatible software for controlling your DSLR’s shutter is available from a number of sources including:
