I've upgraded one of my imaging setups [ 10in SCT at F8 with a Starizona LF SCT reducer, OAG with ASi178mm guide camera, CEM120 mount] from an APSC Orion Starshoot Pro V1 camera to an APSC ASI1071 MC Pro camera. I am happy to report that AA8 64bit SP5 + ASCOM 2.73 works as expected with the 64bit camera drivers.
The ASI1071MC Pro is 16mp vs 6mp for the SS Pro v1 but downloads an unbinned image in less than 1/4 the time plus it has closed loop cooling vs open loop on the SS pro.
