Personally Vind. I wouldn't bother cleaning the optics unless they are really really really bad, you've only had them a week or two haven't you?... If you cant notice it when viewing and you accidently scratched the EP while trying to clean it you'll kick yourself for weeks!! The corrector plate on my LX200 is filthy from all the dew etc over the 18+ months I've had it - I've even had bits of leaves etc stuck to it from the dew etc, also my diagonal which I only use for visual work is also filthy - its primary role is as a dust cover for when the scope is unused
yet with all this crud on both the corrector + diagonal (plus all the crap on the EP's) the views are still great with no noticable hint of obstruction/loss in light transmission from the oil, crud, pollen + who knows what else is stuck to the lenses/glass
....yeah theoritically all that crud does affect the light as it passes through but its basically unnoticable to the eye....to me its not worth the risk of damage for basically no noticable change in cleaning a little bit of oil etc... just my opinion mate
