. they will always seem clear to you becauase your eye is focussing on what ever it is in the secondary

you need to get the secondary mirror pointing to the center of the primary, then adjust the primary to focus the light cone into the middle of your ep. this is what the cheshire does. And why eric was saying. It might take many iterations of moving the secondary, then adjusting the primary. to get it right. A laser collminator does the angle of the secondary regardless of the tilt its only when the laser is returned the same place that it left is when you know the mirror tilt is right.

Getting the center mark on the SW mirror lined up with the dot on the cheshire is the goal.

Its very easy once you figure out what the light path is doing. and will give you beautiful clear pictures.!
