Unfortunately technology to do that off a single imaging device isn't available. To do long exposure on faint objects with low signal to noise you need slow read times during which you read and wipe the entire sensor (usually many minute exposures) to keep noise to a minimum. For guiding, you want 1-5 sec exposures. Closest thing currently is SBIG like setup with small guiding chip and separate larger imaging chip.
