Dr. Strangelove,

Set the tripod the desired distance in front of where your gun muzzle will be (I keep a piece of string for this). Open the bolt of your rifle and put a safety flag in. Put a laser bore sighter in the gun and get the gun set up on the bags so it is aiming at the target. Turn on the bore sighter and use a piece of paper or the palm of your hand to find the beam and set the skyscreens up so the beam is centered in both. Five minutes, tops.

The CED is the only unit on the market I am aware of that started using self-adjusting sky screens that change their sensitivity with the ambient light. It should have fewer problems with light conditions than most.
