ASI CCDs for long FL

I’m looking to match an ASI CCD to my C11 ( with .63 reducer) - with FL around 1700mm (depending on how much backfocus you use). And I want to use a OSC CCD. So binning is not an option. The answer seems to be to go for larger pixels. I have an old SXVR-H9 with pixels of 6.75 but even that is getting close to being over-sampled. But I want to stick with ASI if I can and therefore I am Looking around the ASI range and haven’t come across any obvious candidates.

Does anyone have any suggestions?
