The one place left for CCD's on great big scopes is the ridiculously faint.

Ta M&T. This new CMOS kid on the block won't be replacing my STX16803 anytime soon. I re-shot the same field last night with the CCD and it wipes the (noise) floor with the CMOS. (I am putting together a small test report and will post a link soon). Sure the QHY has better resolution, but the bigger CCD pixels have recorded just a much, if not more, nebulosity with a buttery smooth background that makes the CMOS look like sand paper.
Weather permitting I will re-shoot the scene with the QHY, dithered & shorter exposures, but same total exposure time.
It expect the result will be interesting!
