Hi Morgan;
A 2x barlow belongs in the diagonal prism then the eyepiece. This will double the magnification of any eyepiece. If you put the barlow in the draw tube then the prism then the eyepiece, you have now turned it into a 3x barlow. Using it this way will triple the power of any eyepiece. Some scopes with a short focal length cannot focus at 3x. The focuser cannot reach the focal point. That could be the probelm.
That's it;
BOB SAL
