Hi. We are considering using dual AFW-10 filter wheels to replace our Apogee filter wheel at Madrona Peak Observatory. Can you tell me the thickness of the AFW-DUAL adapter that fits between the filter wheels in dual configuration? We need to calculate the adapter thickness between our field flattener and camera and so need to know how much that spacer adds to the 0.55" x 2 width of the two filter wheels. I've looked through all the documentation I can find online and haven't been able to come up with the AFW-DUAL thickness. Thanks, Walt Cooney
