Rowland, I agree that the argon filling can be problematic, and the bag is a pain to install and seal while providing exit points for the intervalmeter, battery eliminator cable, or USB connector. I have used it with just the intervalmeter and the battery eliminator exiting the bag at the same point but have to assume it leaked somewhat despite being taped up. I have bought a water proof camera bag from ebay but it is junk and no better than a standard ziplock bag with an adaptor cutout. Dedicated underwater boxes for the Canon are a good solution but they add too much weight to the focuser, and cannot seem to be adapted for focuser attachment. So I will continue to work with the bag. I have a dark site trip coming up so a good field test is looming.
