MetaGuide

MetaGuide is a multi-function telescope autoguiding and collimating tool based on real-time image processing of a video stream.

All it takes is a video camera (USB, Firewire, etc.), or an analog video camera (NTSC or PAL) connected to a video2usb converter. For guiding, you need either an ASCOM connection, GPUSB, TOGA, QHY, ASI, AstroGene, or LPT port interface.
