Thanks Gents,
Yes it does fit on an eyepiece & after Malcolm's suggestion I googled parfocalising rings & agree that is what it most likely is. Hadn't seen one before.
Cheers

I think it is what Malcolm suggests.
So you use one ete piece and you find when you change to another you need to refocus but using the ring you dont move the focuser but only the eye piece and when focused secure the ring so you can switch between eye pieces without moving the focuser.
