Hi, unsure if this helps but I bought a triple bracket on Ebay that holds
3 finders in the place of one.

With this, my scope carries a right angle 7x50 finder, all metal straight through finder with led circle and an Orion 70mm F4 finder with 21mm Hyperion for 13X. A bit of extra weight but fine on my Dob. Bintel sells a double bracket (no stock) at nearly 4X the ebay price.
It's an excellent item that will morph on to any scope with a standard finder bracket
