I tried mounting the camera lense under the front of the dovetail on the refractor but it was very hard to balance and point. But my 800 lense weighs 3.5 kg and the whole assembly is quite long. . Side by side worked and point aligned first time and guided fine so I can see why this is widely used. Might depend on the weight and length of the lense assembly.
