G'Day Allan, I just use a 2" Camera adapter. I also blow the camera out with a hot hair dryer and seal it up very quickly. I have just aquired a bottle of Argon gas which I can now purge the camera and adapter with in a plastic bag then assemble and use.

I have tried storing it in a plastic bag with dessicant or with the heater and it still happens.
The only shot I have done that didn't give me a reflection was a Horse's Head shot with the Megrz110 and a Flat II(which I just can't seem to get the spacing right still!) with which I used the original noise piece with no glass>an Astronomik UV/IR>a version of Marc's adjustable spacer(thanks for the diagram)>Flat II>extension>IDAS LPS P2 filter on the end in that order.
I then ended up with blocky stars- is that what is called undersampling?
I would like to find an answer, as I'm getting ticked off and am considering selling the QHY8, or perhaps we need some collective pressure on QHY to help resolve the problem.

Hot hair dryer is the way to beat it.
