I'm not meaning to be a nay-sayer but as I say to a lot of people. If it works then don't change it.

Many astro cameras are gas-tight, and it takes years for the gas to leak. QSI, FLI, ATIK 16200, SX-46 and 56 models, perhaps SBIG and MORAVIAN just to name a few I know of. Eventually though argon leaks from the camera and thus normal air gets in. Since these cameras are designed to have argon within the chamber and work better with it, hence imagers either refill their cameras themselves or send their beloved cameras on a long trip for refilling at the factory.
