This is neat: some Pentax cameras that have GPS, a compass, and most importantly a sensor attached to small motors that allow it to move inside the camera (normally used for in-body image stabilization), also can compensate for the movement of stars in a photo by rotating the sensor to keep the stars stationary relative to the camera. The GPS is needed to tell how the stars overhead will actually rotate.
I assume that this means that anything stationary on the earth will be blurred instead, but still very cool.
Yes, part of the “art” of stacking is choosing a location where you can easily create a mask that covers the sky but not the ground to avoid blurry artifacts, and then blending the two sections seamlessly.
