I find the polar scope close to useless from my light polluted skies visually. It is possible to put a camera at the eyepiece to help with the alignment procedure - afocal.
There are other ways of doing a polar alignment without a polar scope on an EQ5 mount like yours. There's one particular IIS thread I want to give you a link to that I struggling to find. As soon as I find it I'll post it.

Thanks Alex,
Yes, I think it is an older polar scope option that was not taken up by the original buyer. The newer polar scope on offer apparently replaces the whole of the older unit so it means unscrewing the older unit completely and screwing in the new one. I am told SW changed their polar scope design and so those units that had already been produced and remained in stock went out the door with the older unit in place.
