Hey Michael,
For my Meade 12" dob I bought a Stellarvue binoviewer from Pete at SDM.
They came with two little extra items. looking like a pair of small barlows, which together made up the optical correction system that has been mentioned. I was warned I may need to use either, or both, and in fact I have to use both to get focus.
So don't despair, these items will get you going. And I'm confident you'll agree it's worth it once you get sorted out. They bino views are spectacular
