I wasn't citing anyone in particular, but commenting on the thread in general. I wasn't clear on that, sorry if it looked like I was responding to you specifically.

I think there is a Pentax issue here -- the camera shouldn't freeze, even with an incompatible lens mounted. It isn't Pentax's job to make the Sigma lens work, but they shouldn't let it crash the camera.

This would not require a tracking mount. The camera knows exactly how it moved the sensor, so it could simply compute the transform (translation and rotation) to align multiple frames, it would not need to match the images. It is true that the edges of the image would not stack as deeply, or at all, so this would only be practical for a small number of frames.

AstroStacker, combining AstroTrace and interval composite mode to extend effective exposure times. After shooting the first frame to the limit of sensor movement, the camera reads the sensor to the buffer, resets the sensor position and starts another exposure. Exposures are overlaid in the buffer, much like panorama stitching, and the pixel data is composited as interval composite does today. You wind up with a larger, non-rectangular image similar to a stitched panorama, which would require non-standard handling, but in-camera panorama processing is nothing new, so I'm sure it is both possible and practical.
