Brian Sampson is correct.

You will get a sharper and more stable image if the errector tube (and thus the reticle) are opticly centred, I don't know why manufacturers don't set them up to be mechanicly centred, but they are not, at least not on any of the ones I own.

I used to do mine mechanicly, then a very similar thread was started and when I checked, there was in some instances a huge difference between the two. As optical is the one you will use whne looking through it, it makes sense to at least try this method.

Good look
