Have found with an f4 scope and the very small pixels of a 694 that you need the CCD to be precisely aligned with the optical focal plane. Not sure how the two chosen makers deal with it, but it is a big issue and probably worth asking them. Otherwise, as you say, cooling is not such a big deal with this chip - mine works fine at 0C.
