I couldn't tell you off hand what the precise measurements are -
I no longer have a vernier.
I went to the RCC because the MPCC didn't have enough back focus.
It is also a better 3 element design.
I would recommend the Varilock spacer which is adjustable.
On this pic you can see that a small amount of material has been removed from the plastic
filter wheel housing to connect it up the way I have it
with an OAG.
