Also, I image solely from my backyard so transport convenience isn't an issue and I suppose by even considering this route from DSLR to CCD, I am chasing the best possible results from my imaging!
So my question is...Is the 16bit dynamic range afforded by CCDs noticeably superior to the 14bit Cooled DSLRs in widefield imaging?

The M54 thread on the QHY filter wheel is not that common.. I certainly could not find an adaptor to do the job and had to get one custom made (as well as reducing the thickness of the camera-filter wheel connector).
I'm not sure that 16 or 14 bits is the thing to worry about - a lot of other factors are more important. I've got some test shots that give a direct comparison.. will try to finish processing and post soon..
After a few months with both, I'm very impressed with the performance of the cooled DSLR for widefield work. But the h-alpha shots with the QHY9 are also appealing..
