Have a look at the Sharp star 71SDQ, it's a new FPL-53 Quad Flatfield APO just released. I have the TS version, the TS71SDQ, which exactly the same scope. The 72ED scope will not be as good for imaging (poorer colour correction), and is likely to require a field flattener as well. The 71SDQ has a built in flattener, and is an f6,3 focal ratio. It also has a 44mm imaging circle to suit larger camera sensors.
