Newtonian f5 6 inch collimation

Whatever I do, I cannot get the inner reflection into the centre of the focuser so cannot get concentric. Followed astrobaby guide, centering focuser, adjusting with the main screw on focuser, secondary screws and using chesire eyepiece.

The crosshairs of the chesire align with the primary centre circle marker.
Have attached photo but shows worse than what it is.

Who wants to come over and HEEELLLPPPP
Regards
