that was quick. seeing the ZWO shelves empty as fast they can restock must have spurred on QHY a bit.
I guess that CMOS cameras are much easier to design than CCD, since all of the hard bits are on-chip and have already been fine tuned by specialist engineering teams. That should also mean that all CMOS cameras with the same chip should have practically identical imaging performance and they should cost much the same.
