Looks good...
I tried the 2" T-thread adapter with my Ha filter, but my T-thread adapter did not seal up at all.... With the variable T extender + standard nose piece, do you then screw the 2" t thread adapter onto that to insert into the focuser? That would provide enough extension to then not require an extension tube in order to focus I think....
**Meade variable T extender added to shopping list
