I managed to connect the filter wheel to a GSO diagonal resulting in a 44mm clear aperture. It was difficult though due to poorly manufactured parts from Baader.

Baader SCT threaded rings screw into either side of the diagonal body to connect various parts, but both of the rings are too large in diameter and they weren't even identical to each other. I used an angle grider with wire brush and a sanding stone to reduce the diameter of one ring; the other was so oversized I had to cut through one side with a hack saw after which it was still a tight fit.

The end result is good and it's a very useful piece of gear, though the project might have been easier using a Baader clicklock diagonal (assuming you managed to get one of the smaller sized sct threaded rings).

With the ability to quick change filters I'm finding nebulae/nebulosity that is otherwise invisible in my light polluted conditions.
