Hi Neil. Maybe post a pic or 2 of the back of the scope with the eyepiece in so the guys can see the setup. I would’ve expected that you simply need to put in the diagonal then eyepiece into that. No extension tubes. The whiteout indicates it’s not focussed.
I’m tending to think that there’s an extension tube or focal reducer between the scope and the visual back which needs to be removed. You did mention a wedge so maybe it’s last use was in a photography configuration.
