That's my point
The chip would be as big as an A4 sheet of paper!!!
That scope most likely is a Nasmyth focus with a 12" tertiary mirror and at least that for the focuser size. The camera probably has onboard storage and then downloads via a fibre optic link....it's probably the size of two boxes of reflex copy paper and weighs just as much!!!!.
