I have a TMB 130 Refractor. I have a WO Field flattener and a separate 2.7" AP telecompressor (focal reducer). I can attach the focal reducer to the back of the WO/FF, but would that be better optically or should they be used separately for different purposes. Thanks Bill
Looking at the A-P website, at least some of the Telecompressors are also field flatteners, I think you only want to have one field flattener in the optical path.
