This is an interesting project and looks like it could very well be the next Artemis kit. The ICX453 is a decent entry-level CCD and is the same chip used in the proven QHY8 camera.
A fellow from Germany has done something similar with the ICX453 and even went as far as making a complete stand-alone peltier-cooled imager with integrated 8 position filter wheel, OLED screen and compact flash storage.
