DSLR Timer is a DSLR interval timer using the parallel port or serial port of your notepad or PC.
It can control series of long exposures of digital cameras as it is needed for astrophotography. You need a special cable to connect the camera's jack for the cable remote control to the computer. A description of such a cable can be found on my homepage.

DSLR-Timer offers the following functions:

• Single shot (Start - Stop). Mainly for testing the correct setup before starting an intervall series. 
• Intervall timer. This is the main feature of this program 
• Exposure time from 1 second to 1 hour per image
• DSLR Timer can consider the time for mirror lock-up, noise reduction and the time which is needed to save the images.
• Pause-Function to interrupt and continue a series of shots.
• Display of the total remaining time for the complete series, including the time for exposure, mirror lock-up, noise reduction and save.
• Display of the time of day, when the series will be finished. So you can easily go for a coffee and come back in time.
• Camera control via parallel port. You can use LPT1 to LPT3 or any port address. This is very important for the usage of PCMCIA cardbus cards..
• You can specify, which PIN of the parallel port is used to control the camera. Only the one bit which corresponds to this PIN will be changed. The other PINs can be used by other programs. So you can control a webcam with long exposure via the same parallel port at the same time
