If you're really determined to lubricate it use graphite.

I agree, as there are no load/heat issues with this type of bearing I would not use ANY form of lubrication, as this will accumulate dust and other particles which will score, although minutely, the two metal plates, over time.
I have the same set-up on my 16" Lightbridge and all I do is occasionally (annually) clean the two plates to remove any dust or dirty build-up, which is very little in any case. Just depends on where the scope is stored.
