Hi Greg
As you are probably aware, the FLI cameras come with a standard nose piece which fits in the back of the CFW series filter wheels. The Centreline filter wheel that I use is different in that it has ZTA built in. I had to change the front plate on my PL16803 to the ZTA plate when I started beta testing the Televue NP127/FLI astrograph. The astrograph is designed to work with PL cameras because of the ZTA and the critical chip to focal plane distance. The Microline cameras present a problem in this respect in that a Microline to ZTA adapter from Precise Parts takes the sensor chip outside the focus range of the Atlas focuser with my system. I was with Jim Moronski at NEAIC where I picked up my ML x814 camera and he said that FLI had just made an adapter that fits over the standard nose piece of the ML camera, converts it to ZTA and compensates for the difference between chip to flange distance between the PL and ML cameras. I think this came about when Wolfgang Promper wanted to try a ML camera on the other beta test model. Precise parts and FLI can provide adapters to fit equipment such as cameras, OAGS, etc to ZTA equipment such as the Atlas and Centreline, I believe the actual mechanism though is patented
Best wishes
