The DSUSB-IR1 is a USB peripheral for your computer that allows software to control your
DSLR camera's shutter. The DSUSB-IR includes all the necessary cables that
will enable to conect the DSUSB-IR unit to your PC and your DSLR camera.
Many people are now using Digital SLR cameras to take deep-sky photographs.
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 DSUSB-IR1 on this page will
allow you to do so when used with appropriate software that supports this adapter.
For the Nikon D50, D70, D70s and D80, and any other models that are compatible with
the Nikon ML-L3 IR remote control, you will need to purchase the DSUSB-IR1. This
unit comes complete with a 1.83 metre (6-foot) extension cable and an IR
transmitter head that is mounted where it can be "seen" by your camera's
IR receiver.
