Can tilt in the focuser tube be corrected by collimation?

I have a Skywatcher 130PDS scope with a dual speed crayford. I'm using it with heaver imaging equipment than I have been using so I've tightened the tension on the focuser so it doesn't slip, however this has introduced tilt in the focuser tube. I can see the tube on one side has a smaller gap between it and the wall of the focuser.

Does this matter for imaging as long as the scope is properly collimated after the focuser tensioning?

Sounds like the Crayford focuser needs adjusting.  The design should ensure that it does not tilt,  if the focusing tube slips without the locking screw tightened then the other adjustments on the focuser body should address that issue.      🙂

Thanks Peter, I'm still unclear though. Does that mean collimating after tensioning the focuser won't solve the issue?

There are screws on the focuser that allow you to adjust it, but two of them are obscured by the focuser knobs, so pretty useless in hindsight.
