It doesn't matter if the reducer is fitted to the rear cell, inside the focuser or behind the focuser.....the critical dimension is the fixed distance between the reducer and the eyepiece/ CCD.
The mirror shift focus may have to be used to get the best results.
Andrew - the x0.33 is really just an imaging reducer not for visual use. The distance for this reducer is around 55-60mm
