I am using MarkV with 2" OCS in Lightbridge 12" F5. Before purchasing the MarkV, I asked at Baader whether it would come into focus. The answer was yes, but in reality it did not. After some experimenting I lifted the primary by about 1/3" using longer colimation bolts.
Now with MarkV + 2" OCS it is focused when I rack the focuser almost all the way in (only about 2 mm left).
With my Pan 41 it is focused all the way out.
I did not check the vigneting, but at an eyepiece in bino mode image brightness and contrast is as good as in mono.
