[Utah-astronomy] 4 inch focuser ?

We have a 4" eyepiece that we want to check out, but no scope with a 4 inch focuser. We're hoping someone within a few hundred miles will have a scope that they will let us try it in. Jo <<<I have a long focal length refractor but the focuser is only about 3" diameter. Where did the 4" come from? (I have a suspicion) Brent>>>
