Very true, but 80mm aperture is not necessarily optimal for high resolution imaging.
Assuming 80mm f/6 telescope, imaging with 3.8micron pixels might be a bit below a diffraction limit for such instrument, so gain in resolution over using 5.4 micron pixels might not be as significant as we might believe. Moreover, with 5.4 micron pixels we can get data more quickly (important for time-poor astronomers) due to higher sensitivity of larger pixels, and still recover some detail by drizzling. That is why I would be quite tempted to pair a KAF-8300 in a reliable camera with 80mm aperture.
But everyone's priorities can vary, and with certainty ASI1600 or similar would be a very nice choice as well.
