As far as I understand it, Pentax has an anti-shake system to remove blur from hand held camera shots. Unlike other DSLR vendors that put the anti-shake motors etc. inside the lens, the Pentax moves the CCD sensor inside the camera to eliminate the shake.
What they appear to have done is utilised that moveable sensor technology and coupled it with a GPS unit to allow the sensor to move to track the movement of the stars for long exposures on a normal static tripod without getting star trails. Brilliant!
Good on Pentax for doing something directly for the astro community.
This holds so much promise. I wonder if the system could be extended to effectively be an active optics system if you have it on an equatorial mount, and have the sensor move to iron out the errors in your mount.
