Yep. Using a purpose-made 82mm adapter made by Optec themselves for the specific CCD I'm using. The problem seems to be with the interrelationship between the flattener in the rear of the baffle tube and the reducer itself. According to Jeff Dickerson, the manufacturer, the only effect of having a mismatched camera adapter is some vignetting as it can still produce an image down to 22mm. So whatever the problem is, it's in front of the reducer, not behind it.
