If you think about it -
the whole camera should be sealed & then filled with Argon.

That's true with the old QHY8 but with the QHY9 you'll find that you still can image with the main body of the camera opened to ambient air and the CCD chamber will not fog up. I've used it many times with lenses and they're not sealed. Only recently, after 2 years, did I have to regaz the chamber.
