Which one are you thinking of? The QSI690? It sounds appealing but its quite a small FOV which as Mike has shown is not that much of a problem with the 305 F3.8 large FOV, I have the 694 and its low read noise and highly sensitive. I think it would be good for galaxies and its not that great a match for the CDK17 though. The 6303 might be a better match for the CDK or the 4022 chip would be in between compromise for both CDK17 galaxy work and the Honders for smaller objects.
The 51mp FLI Proline is an interesting looking camera. Over 60% QE at peak is impressive. 6 micron pixels would be good for the Honders and not so good for the CDK. Perhaps OK with the reducer but that means back to a guide scope. Perhaps an APM Riccardi reducer may work on the CDK but its a gamble. An AP CCD67 didn't work that well on the CDK. It came to focus but had noticeably degraded resolution over the Planewave reducer.
