Product Description

SBIG began with the ST-4 autoguider over 20 years ago. This venerable stand-alone unit is still used by many for digital astrophotography.  We now offer the SG-4 standalone autoguider.

After two decades of experience making self-guiding cameras and autoguiders, we have developed the SG-4 for those who just don’t want to use a computer to guide or image with their digital camera or non-self-guiding CCD camera. The SG-4 is made to piggy-back on your scope and perform 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.

  • Stand-alone configuration, no control computer
  • Perfect for DSLR users
  • KAI-340 CCD 640 x 480 @ 7.4u
  • Low read noise and low dark current
  • Single button operation
  • Mechanical shutter for automatic dark frames
  • RS232 port for image download and setup
  • Optional Serial to USB adapter

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.
