Generally speaking collimating your APO at home is not the usual action
others may comment on this but I don't think its a simple action and not normally done.

More expensive lens cells do have collimation screws but that's more for the factory technicians not home use.

I have never collimated an APO scope. I did have to fix up an offcentre focuser rotator that was way off square.

If the scope's lenses needed collimation it would be a huge negative for that scope. It should come from the factory prefect and short of a huge fall should never need adjusting.
