Pentax has this feature in some of their DSLRs. The sensor utilizes it's IBIS (internal vibration stabilization) mode of the sensor, but the motion tracks the sky. So, all you have to do is put the camera on a tripod, point it at the sky, and shoot. No separate tracking platform needed. Of course, it has limitations, but it seems like a very nice option in a camera.

The camera used here was a full-frame costing about $2000.00, but they have inexpensive APS sensor models that have or can have added the feature.
