Canon Patent: Image Stabilized Lens For Astro-Photography

Egami (translated) spotted a Canon patent concerning an image stabilized lens for astro-photography. The lens is able to automatically track objects (stars etc). Canon has a DSLR suited for astro-photography, the EOS 60Da (price & specs). Such a lens obviously needs a camera that supports it. That means GPS, levelling, and a powerful CPU.
