SBIG Camera Control
The Santa Barbara Instruments Group (SBIG) provided a number of different CCD cameras and accessories for astronomical imaging. The SBIG package adds operations and functions to Igor Pro (Macintosh-only) that enable it to control SBIG cameras through SBIG's low-level driver routines. This allows you to write Igor Pro functions which can script the behavior of an SBIG camera for whatever application you may have.
