Nick,

 

Once focused to your guide camera, that should be it.  Lock down the fine-focus with the retaining ring and call it done.

I tried the Baader fine focus but in the end I bought a helical focuser which is much easier to use. Screwing and unscrewing the front lens to focus was a pain because it unlocks the lens which has to be locked again.

What is best practice for using the fine focus?
