ASI1600MM-C -> EFW -> Esprit 80 ED

I am getting coma with this combination. The Sky Watcher Esprit has a field flattener I am using, but I am easily getting coma out at 70% of field. Has anyone spacing suggestions?

Thanks,

I figured out my problem. I used the 21mm adapter to connect the camera to the EFW, while the manual clearly states to connect the camera to the EFW directly. I need to learn to read manuals first...
