Colimation of WO Zenithstar 80ED

I have a venerable Zenithstar 80ED and decided as I have a colimation laser to try it out.

The laser returned its beam through the scope and landed within 4mm of centre on the front lens. It looks as if this deflection is due to the focusser not being 100% axial to the lens and doesn't look adjustable.

I was wondering if this sort of deviation is within tolerance for this sort of refracter.

Many thanks
