How big do you want it? The True Field of View of that finderscope is over 5 degrees. They don't come much bigger. The problem is that a RACI finderscope as opposed to a straight through, does not allow you to get behind the finderscope and sight along its barrel and get it pretty close, before you look into the eye lens. On smaller scopes of this size class (ie ones you don't have to climb a ladder to use) I find a straight through finder to be a way better option than a RACI.
I have an 8 x 50 Antares RACI finder on my 18" Obsession in combination with a Telrad. I have an 8 x50 Stellarvue straight through in combination with a red dot reflex sight on my 14" SDM. I have a 6 x30 Williams Optics straight through on my 10" SDM.
All of these work very well for me. I would be equally happy with a straight through on the 18", but I wouldn't be happy with a RACI on the smaller scopes.
A TELRAD on its own can work well. However, if you don't have a DSC system a Telrad on its own can be a bit difficult for some as you then need to star hop in the main scope as opposed to starhopping in the finder. Some people on the other hand are happy with a TELRAD to get them close and then just star hop in the main scope.
