Sam,
You need to wear your distance prescription. Even if you think you don't need it for day to day two eyed vision, you are probably slightly longsighted (don't confuse this with presbyopia, needing reading glasses due to the eye's loss of focussing ability). You need to get a set of distance glasses made up and the focus through them. The telescope will now be focused for someone that doesn't need glasses. You are compensating for your eye's refractive error with the telescope focuser, which is fine if you're the only one using it
