To get a decent looking field you really need the reducer/corrector that goes with it, that brings (If your reducer to sensor distance is right) the focus point in within the range of the original focuser travel.
When I bought mine they had not figured out how to attach the reducer (It is the one for the ED80 in fact) so I had to get an adapter made, but Skywatcher has released one to fit now. The ED80 had an external thread on the focuser drawtube and the ED72 an internal one, I am still mystified by that decision. Apparently apart from that detail they are essentially the same focuser.
From the reducer you would need a 48m to T thread adapter and then T ring spacers and T ring to camera adapter if required to get the spacing right.
