SBIG make a self guiding camera, the ST-2000XCM ...

Mark.


It's not a simple single camera.

It has 2 CCD's in it, one for imaging and one for guiding.

SBIG cameras are not "self guiding" in the sense that they

don't need a software program to do the guiding - they

just offer a second smaller chip that software can use to

guide from.
