I've had no success getting Maurice Gavin's WPO design to work for me. It's a great concept but the available back focus is limiting.
I'm re-building my unit to use a 55mm f 4 collimating lens in a 60mm square box ( similar to the Classic). This will give a compact arrangement and make it easier to use on the Genesis/ ED80.
Photos to follow.
