Hi Janoskiss,
You will need a tube that fits the focuser with a small hole in the exact centre.
Look through the hole at the diagonal mirror. If the Diag is in it's proper place you should see the end of the tube with the Primary mirror dead centred. If not, adjust the positioning screws on the diag until the Primary mirror is dead centre. If you get it right the Primary should take up all or almost all of the diag.
Now look for the image of the diag in the Primary. It should appear in the centre. If not, you can adjust the Primary cell with the adjusters at the back of the mirror cell.
When all is lined up you should see the Diag itself centred in the field of view, an image of the primary filling the diag, a reflected image of the diag centred in the primary and your own eye, seen by double reflection, centred in the diag.
Try that and get back to us.
Good luck!
