I am working on a 10" f6 reflector design using NEWT. I adjusted the parameters such that the 75% illumination diameter equals about 40mm, the largest ocular I expect to use (2" focuser). The 100% illumination diameter is just over 20mm. The diameter of the tube was adjusted so it just clears the 75% light cone without vignetting at the front of the tube.
