The SBIG SG-4 Autoguider is made to piggy-back on your scope and performs its guiding functions without being connected to any external computing device. Simply attach the tracking cable between the SG-4 and your telescope drive's autoguider input and plug in the 12V power and its ready to go. An RS232 port will allow an initial setup for your particular scope and drive after which operation is completely independent. An optional Bluetooth transmitter may be connected to the RS232 port for wireless setup and download of the image if desired.
The KAI-340 CCD has exceptional read noise and dark current characteristics. The mechanical shutter makes taking dark frames automatic, no need to cover the camera or the scope by hand to capture a dark frame. Dark frames are desirable for autoguiding to remove any hot pixels that might otherwise be mistaken for stars by the guider. A (user supplied) Bluetooth transmitter can be plugged into the RS232 port for wireless setup and image download. The SG-4 will also support SBIG's differential guiding (patent pending) by providing power to illuminate an artificial star.
