Just a normal tap with a soft clip-on hose. You don't need any pressure or manifold set up. (see pics)
I do it every time I image. I put the nose piece on the camera and remove the rubber plug on the side then stick the hose in there and let it run for 15s then plug. Done.
It lasts until I open the camera again and store it dry and open in a sealed pelican case.
If you want to do a more permanent thing like a proper sealed chamber you get the camera in a sealed plastic back, fill it with argon, open the chamber then reseal it while still in the bag. That's it.
I use it for my QHY8 as a quicky on the field when it's very wet. That garantees I don't get annoying fogging whatsoever. I've had the same bottle for over a year now.
