gpowers Posted January 26, 2021 Share Posted January 26, 2021 Hi Folks, I have one Focus Cube en route, I have two scopes i use equally, a 115 Triplet Refractor (805mm focal Length), Aluminium tube and 8" Ritchey Chretien (1600mm focal length) Steel Tube. and here is my conundrum, ? Which one do i fit it to, I cannot reconcile in my mind which would benefit the most given the expansion rates of the Materials and focal lengths. or am i over thinking it , chip in folks if you've got any thoughts, or better any experiences ... gary Quote Link to comment Share on other sites More sharing options...
