Peg,

Correct but won't work with that scope IMO. Putting the barlow before the diagonal will produce nothing but "fuzzballs" as the scope will be unlikely to handle the higher magnification produced by using the barlow before the diagonal. To be honest its unlikely that the barlow will do much good after the diagonal with anything other than the lowest power eyepieces either.
