the stability of the mount is the question, as you have to track and guide very accurately you cant have any movement.
once you have a heavy scope on a mount its more prone to wind, vibration etc. some do a rap test , where you tap the tube and see how long it vibrates/ shakes for ... the heavier the tube in relation to the mounts capacity the less stable it is. there is a limit where the mount can work effectively and well ..... usually less than the manufacturer claims
