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.

That film Stone-Age thing won't accommodate the resolution of 24-45mp cameras.

Why you need 40 mpx camera to photo the dark sky?
Even the Hubble don't have it?

The Wide Field Camera 3 (WFC3), which is to be installed during the servicing mission in 2009, will also have 2 CCD chips each of 2048 x 4096 pixels for a total of 16 mega-pixels.
