Its probably something like .2 of a millimetre.

Greg, thanks for your comments!
I think I detected some tilt while collimating. I used a hotech CT laser collimator: same as what Yuri uses in his shop. It indicated a slight tilt but I ignored it as I was getting late to head out to the dark site.
Perhaps shimming it with a feeler gauge as you suggest is easier than fixing in collimation.
