I am reluctantly selling my SG-4 Autoguider that I bought 2nd hand on AstroBuySell just over a year ago as I am funding a new telescope purchase.
This unit works perfectly and has everything you need to connect and calibrate (including Keyspan), and start autoguiding with your chosen guidescope.
The item description I have taken from the Diffraction Limited website.
This is an awesome piece of kit if you want a stand alone guider in the field without the need of a computer!
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.
