aperture settings for camera lens on cooled cmos cam

I've just got an adapter to connect my canon camera lenses with my fairly new QHY268C. Never done this before as there wasn't enough backfocus to use my Canon lenses with my previous FLI camera plus filter wheel.

Silly question perhaps and something I hadn't thought about before, but how do you control aperture settings? If you set the required aperture when it's attached to the Canon camera body, will it remain at this f/stop when transferred to the QHY?
