We had to space Graemes focuser on one side as the laser was pointing off to one side of the diagonal by about 15mm . I am not talking about didgonal off set either . This is towards the side of the tube not towards the mirror . Spacing was not a problem but the play in the focuser could not be removed .

I'd better check the one on my newt as well, think its made by the same people. The slop in the draw tube can be removed, involves glueing some brass shim inside the body. Needed about 25 thou for mine, that is a lot of play. Two pieces the inside length of the focuser body and wide enough to leave space for the rack and the locking strip will take up the side and vertical play. No substitute for a good focuser but every little helps.
